Here's another one:
I've created a method that returns an array of its own class:
anArray: aQuantity
| a |
a := Array new: aQuantity.
a size
do: [:i | a at: i put: self class new].
^ a
but, for a while, I was trying to make this a single line:
^ (Array new: aQuantity) do: [:item | item := stuff ]
This doesn't work (I think) because "do" passes in a value rather
than a reference. I didn't see how it could be done with
withIndexDo: either.
Wondering if I'm missing something.
^(1 to: aQuantity) collect: [:i | stuff]
