The main reason why there are no JS add-ons happening here are preferences of older folks.
Also, for a moment i thought "wouldn't it be nice if pm could remind you to put codes tags on your stuff when it detects you posted perl code". But half the requests in SoPW are too badly written to be recognized as Perl even by the perl interpreter. And the stuff over at Obfuscation is, most of the time, not even recognizable as Perl to experienced humans. So that's another non-starter.
Oh well. But thanks for taking the time answering my questions/suggestions!
