> I'm confused...

I need to find the first regexp that is stored in @syntax that matches, and discard the rest. When one matches, I need the capture groups, if any.

But I'll take the other answer, that a regexp returns true even without capture groups. I could not quickly find any mention of return values in either perlre or perlsyn, both rather hefty pages, before asking. Was probably looking in the wrong place anyway... Ah, yes, I found it in perlop now: 

Matching in list context
       If the "/g" option is not used, "m//" in list context returns a
       list consisting of the subexpressions matched by the
       parentheses in the pattern, that is, ($1, $2, $3...)  (Note
       that here $1 etc. are also set).  When there are no parentheses
       in the pattern, the return value is the list "(1)" for success.
       With or without parentheses, an empty list is returned upon
       failure.

I didn't expect this many answers, to be honest...
