Shame that. I can imagine it being a useful feature in certain situations
(such as a hosted environment), although I understand the concern.
Code obfuscation is the norm, though. The world at large still seems to
believe that compiling code make it secret, despite the fact that crooks
have demonstrated again and again that they're more than willing to read
through opcodes, and the fact that there are decompilers available for
just about every major compiled format.
