<p class="MsoNormal"><span style="font-size:11.0pt">Especially as a new user to Smalltalk, I would suggest leaning into Smalltalk concepts rather than trying to bring functional programming into Smalltalk. Although I can’t think of any, there may be a real
world benefit to curried blocks in Smalltalk. I think this may be a better subject to breach after a bit more mastery.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">A natural reaction to this would be “how would you do it differently?”. That may seem like a fair question, but I think it requires a use case that you are trying to solve.<o:p></o:p></span></p>

<p class="MsoNormal">I wanted to see if it was possible to define a class that supports partial application with blocks. The goal is to be able to pass fewer arguments than a block requires and get back a new "block" that requires the remaining arguments. Perhaps
this has already been done and I just didn't find it.<o:p></o:p></p>
