This file tries to check that all errors above the
field-specifier code in unicodeformat.c and pep3101.c
can be generated.

>>> f()
Traceback (most recent call last):
TypeError: Function expects at least one argument

>>> f(1)
Traceback (most recent call last):
TypeError: First parameter must be string or unicode object

>>> f('{0} {abc', 1)
Traceback (most recent call last):
ValueError: Unterminated replacement field at format_string[5]


>>> f('{')
