In the case of a regex with many, possibly overlapping, matching
captures, I can't see how your interface makes things less complicated.
Certainly in your example above, if you just want to know "what did this
pattern capture?" you could either wrap the whole thing in ONE capturing
parens:
( (?: "[^"]*" | \d+ | \w+ ) )
or use repeated capture numbers:
(?| ("[^"]*") | (\d+) | (\w+) )
In both cases, what is captured appears as capture string 1.

Do you mean (?@ ? I don't think this is in use in PCRE or Perl. At
least, it's not mentioned in the man pages.
