1) 'Some people, when confronted with a problem, think "I know, I'll use
regular expressions."  Now they have two problems.'

2) If you really want to learn regexes, get a copy of _Mastering Regular

"...string iteration isn't about treating strings as sequences of strings, 
it's about treating strings as sequences of characters.  The fact that
characters are also strings is the reason we have problems, but characters 
are strings for other good reasons."  --Aahz
