<arup_r> If I write
class Foo; include Enumerable; endThis code include all methods from

What if ruby would allow us to include just singular methods?
And so forth, so that we could cherry-pick what we want.
This is already possible in some projects, like facets.
But I think they solve it by splitting up the whole
stuff into individual files, and then including
I think it would be nicer if include itself would
support a scope-mechanic.

Wrapper method like
Module#mix may help you.
