That works in Python3, but not in Python2 -- methodwrappers don't compare
eq
In Python, you can write
if C.__eq__ == object.__eq__:
print('class C does not override __eq__')
Does that help?

Well, the default behavior has changed to raise an exception when
using <, <=, >, >=; i.e., inequalities do not have a default
implementation at all. Perhaps that is enough for your purpose? == and
!= still compare by pointer, but you're primarily interested in
ordering her, right?

While porting the BTrees package (split out from ZODB) to Python3., my
first step is to get the pure-Python reference implementation working:
in order to do that, I need a way to check that objects used as keys are
*not* using the comparison semantics
