Does anyone know if there is a good reason why PyUnicodeFromFormatV() does not fail on invalid format string, but copies the format string as-if into the result?
I would like to change this to raise a ValueError instead. PyUnicodeFromFormatV() is used by PyErrFormat(), so PyErrFormat() may now fail with a ValueError if the format string is invalid.
This behavior is inherited from PyUnicode_FromFormat() which documents the current behavior, so you can't change this in backward incompatible way.
