Oops sorry!

This is not a bug, it is a feature request.

I am not sure how to move it to features now, sorry. :(

On IRC someone asked a nice question:


<arup_r> If I write class Foo; include Enumerable; end This code include all methods from Enumerable. But suppose I want to include #all?, #any? .. What's the way to include only required methods ?


This prompted me to write this.

What if ruby would allow us to include just singular methods?

Something like:

  include Enumerable::any?

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 
this.

I think it would be nicer if include itself would
support a scope-mechanic.
