Collections always return results on an new instance of its own #species.�
That is fabulous to me.� It is what's desired most times.
With that in mind, if you expected a bag or something else, you should convert (asXXX) before the collect.

Subject: [Pharo-project] aSet collect: answers aSet??�
Hi guys..
This morning some students came with an exercise like this:
(Set with: 1 with: 2 with:3 with:4 with:5) collect:[:e | e even]. a Set(false true)
But they don't want to get aSet, (regardless this particular example doesn't make sense)... the question is, why if I send collect: to aSet I get aSet and not aBag? What happens if I *want* repeated elements after the transformation? :( And when did this behavior change?
