Re^5: regex switch trouble

Well, okay, thanks... I really don't enough about the perl internals involved with this operator to assert otherwise, and I'll admit I was "guessing" about this (hence the hedging phrase "...I think...")

Still, perlop does describe the "e" modifier in s///e as: "Evaluate the right side as an expression", and I have to wonder whether this kind of evaluation (whatever kind it is) may have enough in common with "string eval" to have a similar effect on source filters and the Switch module. Based on evidence in the thread, it apparently does.

Thanks for the pointer to the "Apocalypse" pages.

Still, perlop does describe the "e" modifier in `s///e` as: "Evaluate the right side as an expression", and I have to wonder whether this kind of evaluation (whatever kind it is) may have enough in common with "string eval" to have a similar effect on source filters and the Switch module. Based on evidence in the thread, it apparently does. I think (too!) it merely makes or can make a hell to "parse", the rationale being, in any case, that one can happily use `/e` without feeling guilty but should do so if tempted to use `/ee` too.
