Thanks Robert. Another great example of the "TIMTOWTDI-ness" of ruby
and how one's view gets shaped by where they started from.

I have a slight preference for the one that includes the range. It
tells me just a little bit more about what the intention is. Obviously
that's just a matter of taste, or lack thereof.

I still haven't figured out why it works under 1.9. I guess
String#succ has changed.

Cheers,
Ammar
