Unfortunately, this doesn't work. cperl mode in emacs can prettify
perl code, not to mention B::Deparse. For instance:
perl -MO=Deparse -e 'print while 1'
prints...
-e syntax OK
print $_ while 1;
It basically deparses the perl parse tree. It gives pretty good
output; not perfect, but getting there. Plus it expands and
simplifies some things, such as the implied $_ above. It's quite
useful for figuring out messy obfuscated perl.
Even compiled perl would suffer from this problem. At least when you
compile to C or Java the parse tree doesn't follow you around :)
