I think that just means the definition needs a bit more finesse.
It would be a reasonable goal for it to give back *some* NaN
with the same flags and payload as the original.

Sure, but we have that already:

>>> from math import inf, nan
>>> eval(repr([42, nan, inf]))
[42, nan, inf]

The only difference is the `math` namespace vs `builtins` namespace.

The dead increasingly dominate and strangle both the living and the
not-yet born.  Vampiric capital and undead corporate persons abuse
the lives and control the thoughts of homo faber. Ideas, once born,
become abortifacients against new conceptions.
