ManyToMany or reverse to many relationships should have a reasonable way
to interact with them without them touching the database.
It's hard to think about what this would look like, but it could look
something like:
{{{#!python
>>> user.groups.set(users)
>>> user.groups._cache == users # Very explicit, unlikely to mesh well
with future access code
... True
>>> user.groups.all() == users # Via prefetch cache. Nicer but could be
confusing
... True
>>> user.groups.save() # explicit commit
>>> user.save_pending_m2m() # saves all m2ms with a pending update
}}}
