Thanks for the tip, I'll use hash look-up in refactored version. + I was wrong about numification, the picture remains the same with string comparison (hello, AI). The unexpected outcome (for me) is "never access $1, etc. more than twice per regexp executed, but assign results to throwaway lexicals instead. Even if 'access' is masked/folded in loops". Interesting. The exception of any_cr remains unresolved mystery. Thanks everyone (except "AI" with its rubbish, which was NOT interesting). Disappointed as usual about the latter.
