A nice effort. I think this has been tried before, but I don't know the node offhand. Maybe it was a discussion on scripts to make scripts more obfuscated instead of vice versa.
in reply to Deobfuscator: the struggle for light!
But, remember that many obfu's depend on their whitespace, since you're blindly collapsing it down. For example, just try to run Camel Code after it's been sent through your script. Or, see what happens to Things are not what they seem like.. Test this on a few of BooK or Erudil's obfuscations and I bet they will break too.
The best obfuscations abuse the more exotic features of the language, which makes them that much harder to deconstruct.
Also, you might have better luck if you try to run scripts through B::Deparse, by running perl -MO=Deparse file.pl > file.pl.deobfu
