There are too many factors for a better solution to exist.
Let's say we change the method to return a Bag. Some will say it's better
that way, because the resulting collection has the same size as the
And some people will say that you broke their code, because the following
will return false instead of true:
| s t |
s := #(1 2 3) asSet.
t := s collect: [ :each | each ].
s = t
IMHO the best solution is still to replace sends of #collect: with
#collect:as:, but it's a lot of work.
