# mypy is special in that they distribute a C extension only for CPython,
# and while it looks like you are supposed to be able to do
# MYPY_USE_MYPYC pip install --no-binary mypy
# to compile the C extension yourself, I get an error when I try that.
# So instead, clone their repo and build it from there.
