And here, ladies and gentlemen we have, once again, our prime exhibit of stupidity and unwillingness to learn. There really is no other like him in the monastery.

You have doubts? Perhaps you think I am being uncouth and should admonish the poor creature more kindly? I will put your minds at ease with just two simple exhibits:

Exhibit A (posted by the kindly orbtwo):

The inside of a [...] is a bunch of chars, not a bunch of strings, and certianly not another regex. [\d|\.] doesn't mean a digit or a dot, it means a digit, a pipe, or a dot. [\d.] would be a digit or a dot.

To which our valiant Sir Doesntwannaknow replied (Exhibit B):

... something like the following: ...

m/^([^,]+),([^,]+),[\d|\.]+,[\d|\.]+,[\d|\.]+,[\d|\.]+,,[\d|\.],[\d|\.
+]+,[\d|\.]+,[\d|\.]+,,[\d|\.]+,[\d|\.]+,[\d|\.]+,[\d|\.]+/

I rest my case and fall over laughing.
