Sidenote: that's actually a reference to a usenet post from 1997 by Jamie Zawinsk, a Netscape engineer and the driving force behind the open-sourcing of the Mozilla codebase. In the original, Zawinski was talking about regex:
> Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems.
Zawinski's post, in turn was a reference to a 1988 sigfile from John Myers, quoting D. Tilbrook:
> Whenever faced with a problem, some people say "Let's use AWK." Now, they have two problems.
"Some people have a problem and think they can solve it with XML. Then they have two problems."
