So, the __import__ in pickle fails -- indeed, __import__('foo') when
'foo' ``is imported from a subpackage'' is _supposed_ to fail, as
'hyper' is not the name you SHOULD be importing. For example,
is fine, but just
fails with ImportError -- there IS no toplevel module by that name!

If you can't fix the modulename given by your type, you can perhaps
kludge things up by (e.g.)
before you pickle; but I suspect UNpickling would fail in that case.
Using the standard library copy_reg module to register your way to
pickle and recover instances of your type might work better.
