- """ Exports a no-op 'cython' namespace similar to
- https://github.com/cython/cython/blob/master/Cython/Shadow.py
- This allows to optionally compile @cython decorated functions
- (when cython is available at built time), or run the same code
- as pure-python, without runtime dependency on cython module.
- We only define the symbols that we use. E.g. see fontTools.cu2qu
