Those don't take up any space in the actual compiled opcodes. The only space you could save is in the string that the file is initially loaded into and the $eval string that gets built up to pass to eval(). It's probably not worth pursuing, since the savings would be small and there is a risk of breaking code (parsing perl is hard). If you want to see how much it could possibly save, try just stripping a single file before feeding it to Registry and see how much of a difference that makes. > I suspect that mod_perl is stripping them for me. Nope, it doesn't do anything like that. > But isn't a > large string allocated in RAM prior to the eval? Yes, the $eval string is as large as the full contents of the file. - Perrin
