What parties?  I don't think anyone has claimed to actually have used
non-ASCII digits with float(). Of course it is fun that Python can
process Bengali numerals, but so would be allowing Roman numerals.
There is a reason why after careful consideration, PEP 313 was
ultimately rejected.

BTW, it is common in Russia to specify months using roman numerals.
Maybe we should consider allowing datetime.date() accept '1.IV.2011'.
