I missed enumerate() for a while, and was happy I found it. I find it amusing how satisfying a few missing keystrokes can be.
On a related but different note, from a similar influence, I keep wanting to pass blocks to iterators. Any chance that will ever happen? I realize that do..end blocks are used currently as syntactic sugar for methods that take a function as the first arg (e.g. open(), map()), and the same functionality can be achieved with three letters and two braces (map), but it still seems somewhat cleaner to write: enumerate(a) do i,x ... end over map(enumerate(a)) do i,x ... end which are really just equivalent, as we know, to for i,x, in enumerate(a) ... end Are there technical reasons this is a bad idea to assume?
