Hmm, how about this:
str(obj, ifisunicode_decode_using_encoding='ascii',
ifisinteger_use_base=10,
ifisfile_open_and_read_it=False,
isdecimal_use_precision=10,
ismoney_use_currency='EUR',
isdatetime_use_format='%c')
and so on ?!
Or even better:
str(obj, **kws) and then call obj.__str__(**kws) instead of
just obj.__str__() ?!
Seriously, shouldn't these more specific "convert to a string"
functions be left to specific object methods or helper
functions ?
