But I think such a function would be more useful if extension types
can play along.  I mean, there's fairly good lore about the memory
footprint of built-in types, but it would be much harder to figure
that out for some 3rd party extension type you grabbed off the net.
So I think it would be much more useful in the latter case.

This is an important point, so I'd prefer sys._sizeof().
