Well, dang!

I'd recommended using index because of (inter alia) some gnarly behavior with empty patterns. But it turns out it was even more gnarly than I thought.

BTW, perlreref says

If 'pattern' is an empty string, the last I matched regex is used.
What is the 'I' in 'I matched'? I couldn't find it mentioned again in perlre or perlreref, and searching on 'I' turned out to be ... overproductive.
