localeconv() takes no arguments, and returns B<a reference to> a hash.
The keys of this hash are variable names for formatting, such as
C<decimal_point> and C<thousands_sep>. The values are the
-corresponding, er, values. See L<POSIX (3)/localeconv> for a longer

example listing the categories an implementation might be expected to
provide; some provide more and others fewer. You don't need an
explicit C<use locale>, because localeconv() always observes the
