Sorry, I misses the "all" part at the end (I don't see how that could add something, but if it's in the requirements...) Then it should be like this: String streamContents: [:stream | gifts allButLast do: [:each | stream nextPutAll: each ] separatedBy: [ stream nextPut: $,; space ]. stream nextPutAll: ' all, '; nextPutAll: gifts last].

Maybe this is a better way to build what you want. String streamContents: [:stream | gifts do: [:each | stream nextPutAll: each ] separatedBy: [ stream nextPut: $,; space ] ] Esteban A.

You got it. Thanks, Ben! After success with Lua, now I'm thinking about how to get Pharo inserted into the culture here...

I beg your pardon.. and thank you for being the first to draw my attention to the fact that the phrase (a common enough American colloquialism) is actually a logical fallacy. Until now, it's been strictly idiomatic to me. And thank you for your prompt reply. Am I safe to assume that blocks in Smalltalk, as with Lua, capture their locally-scoped variables (referred to in Lua as "non-local variables") for correct evaluation in other contexts, such as when blocks are passed as arguments and return values? I.e., cases where the local variables of a method have gone out of scope and no longer exist, yet are referenced within the block at some future time when evaluated. I expect so; I just haven't seen it described in this detail. -t -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
