Describe the bug

Cythonization of .pyx with fused types when cimport_from_pyx=True stopped working recently.
It was working on 3.0.0b1 and it does not work now on 3.0.5. I didn't dig into when it stopped working exactly.

Here's the error:

  tree = Parsing.p_module(s, pxd, full_module_name)

My setup.py:

from setuptools import setup
from Cython.Build import cythonize
import Cython.Compiler.Options


Cython.Compiler.Options.cimport_from_pyx = True


setup(
    name='Hello',
    ext_modules=cythonize("hello.pyx"),
)

Code to reproduce the behaviour:

ctypedef fused float_or_int:
    float
    int

cpdef function(float_or_int a):
    pass

Expected behaviour

It should get cythonized and compiled successfully as it was before
