Cython coverage tool blames that function definition lines are not covered

I’m trying to enable a coverage for cython modules for multidict library. Cython.Coverage plugin works but the coverage output looks incorrect.

The tool blames that method definitions are not executed lines but it’s definitely wrong because method bodies are executed and test covered.

What I do wrong?

Thanks for investigating @anthrotype. I’ve created a PR for adding the necessary line trace.

The binding directive is generally a good idea, mainly because it improves the Python compatibility of Cython compiled functions. However, I would not recommend using it only for testing, since disabling it for production changes the behaviour there.
