My suggestion was to remove the generic Show instance and add only
specialized instances.  This is more work, but will also yield better
results.  In particular, it allows specialized string representations
for other types, too.  For example the way values of type Vector Bool
are printed is extremely useless.  I always find myself writing my own
debugging output functions for boolean vectors.
