thanks for the pointers! =)

I'm still hoping to find something simpler w/o needing to compile XS-modules, preferably within the core.

Maybe my hack in Re^2: Is there really no @LAST_MATCH_START equivalent for named capture groups? is of help for you!

Cheers Rolf

      Thx for the links but thats Chinese for me.

      I'm not a versatile C programmer and AFAIK even C gurus get depressed when diving into perlguts.

      (BTW: the first link is defunc)

      that would be nice...

      What exactly do you mean with "debug messages"? The token tree with commands like OPEN1?

      Or just message like

      anchored "1234" at 0 (checking anchored) minlen 4 Freeing REx: "(?<C>1)(?<D>2)(3)(?<A>4)"

      The latter I don't need! =)
