Argh. zipfiles are way to complex to be writing. If you want to use zipfiles, compile your whole world ahead of time, stuff it into a zipfile, and install / distribute that. But for the automatic writing of bytecode files as a side effect of importing the source code, please let the filesystem do its job.
