That's a valid criticism, but maybe python could still warn about the
mismatch, even if it would not reject the program by default.

I agree, but there are also environments that I can determine not
being able to run my code, and then I could warn on those.
As to CPython, etc., maybe those can match against a "normalized"
version number that they claim to be compatible with.

I guess you are right about that. And for the really important cases,
I suppose performing a check in the makefile, or, if everything else
fails, directly in the code (yuck) should suffice.
