I worry that an intermediate binary file format, and the code to create
and parse it, would be an obstacle to further improvement.

On the other hand, if this makes someone happy enough to work on other
gmmproc features, such as using gobject-introspection typelibs instead
of .defs, then it would be socially worthwhile.
