There are (unfortunately) no comments in the compiled code, you can check it with B::Deparse.

But I think you have wrong understanding of "compiling" in perl and what you really want is to obfuscate your code.

Actually (in most cases) B::Deparse will produce code without comments.

You may also want to check if perltidy has an option to strip comments.

UPDATE: here they are http://perltidy.sourceforge.net/perltidy.html#other_controls
