I'll put in (yet another :-) plug for String#split:

  str.split(//).each ...

I think the idea of having String#each take a regex is, essentially, a
kind of compression of this -- in other words, instead of #split'ing
on a regex and then iterating through the resulting array, moving the
regex intelligence into the argument to #each.  I'm of two minds about
the merits of this, but in any case I don't think there would be
anything possible in the language that isn't possible now.
