gzipped modules and datafiles

[Klaus Schilling <Klaus.Schilling@home.ivm.de>]

Is there a straightforward approach to provide support for writing to/reading 
from gzipped files, and maybe ports in general? Would an interface to JL 
Gailly's zlib be useful for that? Python seems to have something in that 
direction, but I don't understand how that concept works there, even less if 
a similar concept could apply to guile.
