Or if that's too heavy (two whole characters, plus the suffix!) perhaps
we could have a rule that the suffix must follow the final underscore
of the number:
8_M # int 8*10*6
123_456_789_M # int 123456789*10**6
123_M_456 # still an error
8._M # float 8.0*10**6
This sounds better IMO. It's not legal syntax in any version of Python
older than 3.6, so there's minimal backward compatibility trouble.
According to Wikipedia, it's recommended that there be a space between
the number and the units, thus not "1kg" but "1 kg".
As we don't put spaces inside numbers in Python, insisting on an
underscore instead would seem to be a reasonable compromise.
