[ENH] Compilation does not support importing cython module from another module about cython HOT 4 OPEN

I think https://github.com/sqlalchemy/sqlalchemy/blob/d3222a31b8df97a454b37a32881dd484a06e5742/lib/sqlalchemy/engine/_processors_cy.py#L16-L24 is more related to #1981

What they're really looking for is the ability to work uncompiled and in environments without Cython (where import cython will fail completely)

from cython.

Looking at the "Falconry" issue I think they're trying to do the same thing and essentially provide their own copy of "Shadow.py". I can see why they're doing it, but I still think the right solution is to distribute "Shadow.py" as a lightweight standalone package that people are happy to have as a runtime requirement rather than to try to follow imports through Python modules.

I agree that we should rather do #1981 than tracking arbitrary (runtime) imports across modules, including modules that are not even compiled, that might not be available at build time, or that happen to have the word cython in them.

Now when I am looking at it again, I agree with @da-woods and @scoder. I think closing #1981 will eventually close this issue.
