Is it necessary to restrict "," to decimal? Why not make
"," and "_" orthogonal?

Nick suggests:

This looks very good and general. I only know of the "European" and South

But it's still much less general than having the option in the
f-string/.format() mini-language. This is really about the formatted
string, not necessarily about the locale. So, e.g. I'd like to be able to

is generally written as '1,00,000'.
In turn, a crore is 100 lakh, and is written
