Hi - is this a homework question? While anyone here can tell you what it does - its probably more helpful to you to work through it and properly understand it.
You haven't shown what the output is when you try it - which will give you a clue. Equally - in Smalltalk, the names of selectors like: #do:separatedBy: convey meaning (which is why we like to use good names, that hint at what parameters do). Finally - have you looked at the implementation of the method? The nice thing about Smalltalk is that there is very little magic - you can see the code that runs for operations - including things like #ifTrue: . Why don't you position your cursor on #do: and press ctrl-m (or cmd-m - for show iMplementors - its also in the context menu). This will let you see the code and you should be able to work it out. For fun - try doing the same for: 3 = 3 ifTrue: [ 1 + 1]. Finally - its also worth understanding [1+1] + 1 (and why it gives an error) whereas: [1+1] value + 1 dosn't.
Hope this helps.
