I have been thinking a little bit about a complete redesign of the
module files.

Ideally, I would like it to be an extensible binary format, which uses
a keyword-value combination and which could be accompanied by a "dumper"
which makes it human-readable.  A simple yacc grammar could handle
both the reading and making the "dumper".

If this is designed right, it might not even be necessary to bump the
module number for old library files.
