[Cuis-dev] What is the meaning of "::" in code examples ?

[Luciano Notarfrancesco]

Actually the line

   lay1 beRow :: borderWidth: 1 :: borderColor: (Color black) .

looks sort of sarcastic to me, if code can be sarcastic. Because :: is
normally used to avoid writing parenthesis, and it has unnecessary
parenthesis around Color black. And also the first :: is not needed. In
standard Smalltalk-80 syntax that line is equivalente to

   (lay1 beRow borderWidth: 1) borderColor: Color black.

which is also not very easy to read. IMO it would be better written as

   lay1 beRow; borderWidth: 1; borderColor: Color black.

because otherwise you’re assuming that beRow, borderWidth and borderColor:
return the receiver (not a crazy assumption, but unnecessary). All a matter
of taste and style anyway.
