The problem is that it's still tricky to get at the parse tree. All the parts are there -- named captures, relative backreferences, recursion -- but you still have to litter your regexp with hairy use of
(?{ local $FOO{blah} = $^N })
to get the data back.

It should be possible to whip something up with re::engine and Regexp::Parser, but a brief attempt showed me that this is somewhat tricky to get right except in simple cases. It would be much more convenient to have this support built into the regex engine. Perhaps for 5.12...
