ozo, what is the advantage in your method?

ozoCommented:
It works even if $y contains regular esxpression meta characters (/\Q$y/ would do the same)
it can be faster, since there's no need to compile a regular expression (but you should Benchmark, if you're really concerned about that)
and it demonstrates that there's More Than One Way To Do It.
