This is a curiosity question that will hopefully help me understand the
Squeak *system* better.
I have an Aida application in which I find myself doing a lot of list
manipulation, and given the reputation Smalltalk has for the strength of
it's collection classes, I felt sure I would find a method SOMEWHERE that
exchanged two elements.
So...am I just no good at finding what I'm looking for (swap, exchange,
move?), or is it because it is so simple to write something like
exchange: index1 and: index2
|temp|
temp := self at: index1.
self at: index1 put: (self at: index2).
self at: index2 put: temp.
that no one would even think of needing to include such behavior?
Again, just wondering so I can "measure" my understanding of how little I
know and better gauge whether I think I can find an answer from the system
itself...
Of course, the answer is probably "why don't you just..." along with a
single line...!
Thanks,
Rob
