Those sound like thoughts very similar to mine. If we're going through
the effort to make an admittedly special-purpose C-generating backend,
then we should probably just export the necessary functionality so
that others could do similar special-purpose backends around the
meta-surface functionality.

Yes, I've had this idea at various times. I've never wanted anything
that would be very complete, (in the cases I've wanted this, I
wouldn't care to get C code to reconstruct the source surfaces, for
example), but it would be convenient to be able to grab snippets of
code or at least some statistics about what operations are being
performed at various times.


Behdad, what's with the top-posting? My reply is now in
reverse-logical order. :-}
