Subject: The peak of the iceberg, was Range cannot loop down and RCR Integer#pred

Hi all

I was just following the thread about "loop cannot count down" and
was about to propose a monkey patched method which might have been
convenient for the poster.

Like e.g. Range#each_down  (bad name I know).

The point is, I cannot, because Range#each is based on succ, and
Range#each_down would be based on pred.

I just wonder if it might not be a good idea to define pred for all
core classes for which succ is defined. I kind of feel stupid not
having suggested that in the first place, now :(.

Opinions?

Cheers
Robert
