It's not current locale settings, it's user's locale settings.
Application can actually use something else and you will overwrite
that. You can also affect (unexpectedly to the application)
time.strftime() and C extensions. So you should move this call into the
_test() function and put explanation into the documentation that
application should call locale.setlocale

I think you should call locale.atof instead of float, since you call
re.compile with re.LOCALE.

Everything else looks fine. The biggest missing piece is support for
unicode strings.
