I guess you could do this, but I can't see it ever actually being used
that way. Do you really want to only specify that you're using commas
for thousands, then find that someone has switched the locale to one
where a comma is the decimal character?
Best to be explicit on what you're expecting. My use case for this
function is one where all of the arguments are known and specified every
time. Specifically it's for implementing 'n' formatting for Decimal or
other numeric types. You will either know the arguments, or want to use
every one of them from the locale. If you're using the locale, just call
localeconv() and use every value you get back. I don't have a
mix-and-match use case.
