# Regression test for the %nokwargs / -keyword interaction.
#
# Built with -keyword so every function defaults to METH_VARARGS|METH_KEYWORDS.
# %nokwargs on a specific symbol must opt it back out to METH_VARARGS. Before
# the check_kwargs() fix, %nokwargs was silently ignored when use_kw was set.

# Positional calls always work.
