Subject: determining common characters from start of two strings?

Hi,

Is there any ruby built-in that might tell me how
many characters match (are in common) from the start
(left) of two strings?  E.g.

 "abcxxxxxx".lcommon("abcdezzzzz")  # => "abc" (or 3)

All I need is the length but a substring would be
fine too.

Figured I'd ask in case I'd overlooked a nicer way
to do this than writing a loop.  :)


Thanks,

Regards,

Bill
