Subject: [ruby-core:18052] Enumerators that know about a block

Hi --

I'm remembering that at one point it was possible to do this:

   array = [1,2,3]
   func = lambda {|x| x * 10 }
   e = array.enum_for(:map, &func)
   e.next
   => 10

But now the result is 1, because &func is ignored.

I'm (a) puzzled by this, since it seems to me that enumerators are
much more useful if they can remember a block, and (b) wondering if
there's some similar replacement technique that I haven't managed to
figure out.
