Are there a small number of function pointers involved (that is, if you
create lots, it's because the data half of the closure changes)? If so,
you could check the function pointer when you see a value tagged as
scheme_closed_prim_type.

That's the only idea I have so far, besides the hash-table technique
that you noted.
