Nope, it wasn't me, maybe Danny.

But I sure agree with it. The problem with Regex is that they can
be just a bit too powerful. To cite another programming proverb,
this time by Bjarne Stroustrup I think:

"C makes it easy to shoot yourself in the foot;
C++ makes it  harder, but when you do,
it blows away your whole leg."

Regex can be like that too.
