Yes, and how to make (if possible) equivalent messages minVal/maxVal
that would return that min and max value, but not only for SmallInteger,
as several other implementations seem to support it, and that should
increase portability while not breaking compatibility.
I guess for floats and bignums that would be ±inf (the other
implementation I saw doesn’t implement ieee754 ±inf, nor, but this time
I forgot to check, bignums).
