Ah, that's something else entirely. Yeah, that is definitely a win for TILs
and other methods that compile to real executable code.

Ah. Well, I still think that the intermediate bits should be saved if at
all possible, but I don't much care if the resulting 'binary' (whether it's
a real executable, or Java bytecode, or grossly optimized perl bytecode) is
translatable back to perl source. If some transformation gets a performance
win but crocks back translation, well, that's too bad. :) Performance wins.
I'd rather folks not strip out the source-ish bits (they'll get sucky error
messages that way too) but if they do, well, they do.
