Does MR_agc_deep_copy work with these version types?
If so, that should be all that agc needs.
If not, these types won't work with agc.

Another related question to ask is whether copy/2 (i.e. MR_deep_copy)
works with these types.  If not, it would cause problems if these
types are used with solutions/2 in `--gc none' grades.

Personally, I think that the "to_" usually makes the code a little
more clear.  So I prefer it with "to_".
