Regular expressions are useful -- I'll give you that -- but I think it's
a little much to say that they are the _most_ useful. Their only
practical use is in highly specialized things, such as validating an
email or writing a parsing engine. My day-to-day use of regex is very
limited and I consider myself a power-user. In email validation regular
expressions make sense, but in testing if something is an integer --
that's going a little overboard.
