Over the years we made a little library with collection extensions
We reevaluated when porting Moose to Pharo.
May be this is the time for people to have a look
Moose/CollectionExtensions or something like that
We use it daily for moose. some of the problems we got where that
Stream sucked.... could only work on array and strings. So we use Nile.
Now we should evaluate.
flatCollect: is a cool one.
Normally we even have tests :)
