djgraham asks:
any way of easily extracting the numerical part of a string+integer
(i'm wanting to find out the next number ina series.. e.g..
"INV1001".next etc. but "INV9999".next changes it to "INW0000"
There were a bunch of suggestions including for a joke:
"INV#{'INV000'.reverse.to_i.to_s.reverse.next}"
Turns out that that is faster than all the options that use regexes:

Anyway, I figured i'd throw this out to the list for a bit of fun. The
idea is to correctly create a string containing the next in the
sequence, so "INV0123" becomes "INV124", but in the craziest way
possible. Use of pack or c extensions a bonus.
Will.
