Well, note that PGE is still very unoptimized at the moment -- so many optimizations that Perl 5's engine has built up over a decade of development simply may not exist yet in PGE. It doesn't surprise me if it runs very slowly -- we'll build in the various optimizations as we go (and we need more tests like this one to find the places worth optimizing!). That said, I've tried compiling the rule in PGE and it turns out that at least the compilation phase is currently taking a very long time -- before the rule even attempts a match. Again, this is not too surprising given the current construction of PGE's parser; the ultimate plan is for PGE's parser to be rewritten more efficently as P6 rules, but we just haven't gotten there yet. I'm still bootstrapping... :-) Anyway, this is an excellent test, I'll see what I can do to get PGE to parse and execute it in a reasonable timeframe. Pm
