Comment (by benjaminjkraft):
Oh, yeah, I can see now how the dummy `__getstate__` might break this,
because it seems like if there's no `__copy__`, `copy` will use
`__getstate__` but not `__reduce__` -- sorry I didn't realize before.
(This stuff is not very well documented so I'll need to look more closely
to be sure that that's the issue but it definitely seems plausible.)
I'm not entirely sure, but the simplest way to solve this is probably just
writing a `__copy__` method for `LazyObject`, either by just proxying the
wrapped object's `__copy__` or by doing something similar to the
`__deepcopy__` implementation. I'm not immediately sure which one of
those is more correct.
