Why not?  You'll need *some* default for decimal_point, and the one
from localeconv makes at least as much sense as a hard-coded default.

I agree that it shouldn't *change* anything in the locale, and any
keywords explicitly passed in should override locale, but if it never
looks at locale, you'll get patterns like

import locale
kw['thousands_sep']=' '

new_util_func(number, **kw)
