If Python wishes to limit the digits allowed in numeric *literals* to ASCII 0...9, that's one thing, but I think that the digits allowed in numeric *strings* should allow the full range of digits supported by the Unicode standard.
I assume you specifically mean that the numeric class constructors, like ‘int’ and ‘float’, should parse their input string such that any character Unicode defines as a numeric digit is mapped to the corresponding digit.
That sounds attractive, but it raises questions about mixed notations, mixing digits from different writing systems, and probably other questionss I haven't thought of. It's not something to make a simple yes-or-no-decision on now, IMO.
This sounds best suited to a PEP, which someone who cares enough can champion in ‘python-ideas’.
