<div dir="auto">Re ”statement“: the textual Smalltalk syntax for message sending is inspired by the English language, in which sentences are composed of words separated by spaces, have a subject-verb-object structure, and end in a period. Variable declarations, assignments and returns are exceptions, because they are meta operations rather than message sends. Grammatically, “statements” makes sense. </div><div dir="auto"><br></div><div dir="auto">– Nessa</div><div dir="auto"><br></div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Jun 4, 2024 at 10:19 Ezequiel Birman via Cuis-dev <<a href="mailto:cuis-dev@lists.cuis.st">cuis-dev@lists.cuis.st</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div dir="ltr"><div><div>I clicked the wrong reply button, and replied only to Mark instead of sending a message to the list. I won't reiterate my full reply which more or less reproduced what Hernán said, adding that <i>statement </i>has connotations of imperative style; but I wanted to share, just as a curiosity, that I searched for the word <i>statement</i> in both the ANSI standard and the Blue Book. Both define <i>statement</i> precisely, as an <i>expression</i> with a final dot, or with an explicit return. So if we were to stick to that formal definition, assignments are not statements at all! Yet the expression <i>assignment statement </i>is all over the place in the ANSI Standard. The Blue Book uses <i>statement</i> more sparingly, mainly for comparison with Algol and for messages known to have side-effects, but defines it in the railroad diagram appendix, right at the very end, also as expressions separated by dots, or an explicit return. As for the method template text, my hypothesis is that the s-word is used in that very sense.</div></div></div><div dir="ltr"><div><div><br><br>-- <br></div><div>Eze<br></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, 2 Jun 2024 at 15:58, Hernán Wilkinson <<a href="mailto:hernan.wilkinson@10pines.com" target="_blank">hernan.wilkinson@10pines.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div dir="auto">Ha ha ha, you are right! </div><div dir="auto">Statements are used in the programming language parlance and in this case as a way to simplify the “receiver message” syntax…</div><div dir="auto">It could say “collaborations” but an assignment it is not a collaboration…</div><div dir="auto">Anyway, the thing is that you were not looking for an statement but for a message … you can say that syntactically the message send (collaboration) was going to be express in a statement, but you needed the message </div><div dir="auto"><br></div><div dir="auto">Cheers</div><div dir="auto">Hernan</div><div dir="auto"><br clear="all"><div dir="auto"><div dir="ltr" class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div style="font-size:small"><div dir="ltr"><div dir="ltr"><div style="font-size:12.8px"><span style="font-family:tahoma,sans-serif;font-size:xx-small;border-collapse:collapse"><strong style="font-family:tahoma,sans-serif"><span style="font-size:8pt;font-family:tahoma,sans-serif"><span style="font-size:small;font-family:tahoma,sans-serif"><font size="2" style="font-family:tahoma,sans-serif;color:rgb(0,0,0)"><span style="font-weight:normal;font-family:tahoma,sans-serif"><span style="font-weight:bold;font-family:tahoma,sans-serif">Hernán Wilkinson</span><br>Agile Software Development, Teaching & Coaching</span></font></span></span></strong></span></div><div style="font-size:12.8px"><span style="font-family:tahoma,sans-serif;font-size:xx-small;border-collapse:collapse"><strong style="font-family:tahoma,sans-serif"><span style="font-size:8pt;font-family:tahoma,sans-serif"><span style="font-size:small;font-family:tahoma,sans-serif"><font size="2" style="font-family:tahoma,sans-serif;color:rgb(0,0,0)"><span style="font-weight:normal;font-family:tahoma,sans-serif">Phone: +54-011</span></font></span></span></strong></span><font face="tahoma, sans-serif" size="2" style="font-family:tahoma,sans-serif;color:rgb(0,0,0)">-4893-2057</font></div><div style="font-size:12.8px"><strong style="font-family:tahoma,sans-serif;font-size:xx-small"><span style="font-size:8pt;font-family:tahoma,sans-serif"><span style="font-size:small;font-family:tahoma,sans-serif"><font size="2" style="font-family:tahoma,sans-serif;color:rgb(0,0,0)"><span style="font-weight:normal;font-family:tahoma,sans-serif">Twitter: @HernanWilkinson</span></font></span></span></strong></div><div style="font-size:12.8px"><span style="font-family:tahoma,sans-serif;font-size:xx-small;border-collapse:collapse"><strong style="font-family:tahoma,sans-serif"><span style="font-size:8pt;font-family:tahoma,sans-serif"><span style="font-size:small;font-family:tahoma,sans-serif"><font size="2" style="font-family:tahoma,sans-serif;color:rgb(0,0,0)"><span style="font-weight:normal;font-family:tahoma,sans-serif">site: <a href="http://www.10pines.com/" style="font-family:tahoma,sans-serif;color:rgb(17,65,112)" target="_blank">http://www.10Pines.com</a></span></font></span></span></strong></span></div><div style="font-size:12.8px"><font face="tahoma, sans-serif" style="font-family:tahoma,sans-serif;color:rgb(0,0,0)"><span style="border-collapse:collapse;font-family:tahoma,sans-serif">Address: Alem 896</span></font>, Floor 6, Buenos Aires, Argentina</div></div></div></div></div></div></div></div></div></div><div><br></div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, 2 Jun 2024 at 11:29 Mark Volkmann <<a href="mailto:r.mark.volkmann@gmail.com" target="_blank">r.mark.volkmann@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div dir="ltr">Thanks for the feedback!
