The match succeeds on yabba already.
- 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'
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
