I haven't found 'finally' clauses in https://github.com/gevent/gevent/blob/master/src/gevent/libev/corecffi.py. Perhaps this code was changed in recent versions.

Yes, I was looking at was git revision bcf4f65e. I reran my AST checker and found this:

./src/gevent/_ffi/loop.py: 181: return inside finally

In any case we now know that this combination is occurred (but very rarely) in the wild.

Looks like it. If we do want to seriously consider changing the grammar, I will download more packages of PyPI and check them.

BTW, ./src/gevent/threadpool.py doesn't compile with 3.7 because it uses 'async' as a variable name. So either they didn't notice the deprecation warnings or they didn't care to update their code.
