[FWP] Comparing strings the hard way

[Ariel Scolnicov <ariels@compugen.co.il>]

Perl's string operations are very powerful, but sometimes they're just 
not good enough.  Case in point: I have 2 strings of the same length.
I need to know which portions of them are equal, and which are not.

  @l = map { length } split /[^\c@]/, $a^$b

gives me the lengths of consecutive equal portions of $a and $b.

Useful fun, that.
