While I agree with your point of view regarding the status quo as a
useful, practical compromise, I need to call out that particular
example:
>>> nan = float('nan')
>>> x = nan
>>> x == nan
False
>>> x in locals().values()
True
Due to rich comparison and the freedom to implement non-reflexive
definitions of "equality", the assignment "x = obj" implies only that:
- x is obj
- x in locals().values()
Cheers,
Nick.
