[issue23699] Add a macro to ease writing rich comparisons

[Stefan Krah]

Stefan Krah added the comment:

The problem with this macro is that most of the time it takes the
standard cmp return value {-1,0,1} and converts that into a bool.

For this use case, it might be more appropriate to use a
static inline function Py_cmp_to_bool().

To put it differently, the macro mostly does not perform the
actual rich comparison but just post-processes the result.


I don't like the dual use of converting cmp() return values
and performing actual comparisons on integers, so -1 on
the concept.
