Re: Regex from Learning Perl

It matches:

a literal "y"
any single character not being a newline (save this in \1), in this case an 'a' is matched
any single character not being a newline (save this in \2), in this case a 'b' is matched
Match whatever is in \2, i.e. a 'b'
Match whatever is in \1, i.e. an 'a'

The match succeeds on yabba already.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
