Is there a way to use collectors to filter a list into a set?

[Alejandro Serrano.Mena]

there's no filter collector right now, although it should be possible to write it (right now, maybe using reduce ?)

[dave08]

And how does that go into a set? The docs don't really go into very much about all this...

Use reduce and initialize it with an empty set
