Yes, I misunderstood his comment above.

"2. In character classes (inside square brackets in a regex) you do not have to backslash brackets. ^ on the non-first position in a character class stands for itself."

When I read 'you do not have to...' I understood that the backslashes are optional, but decided I liked to use them anyway. I completely missed his more important point here, that the repeated ^ actually negates the ^ character.
