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.

A bug in perlreref? On my screen, I see: `If ’pattern’ is an empty string, the last I<successfully> matched` [download] I know too little about POD to say whether this is a problem with the web rendering or a problem with how the file is written.	[reply] [d/l]
