Question: What is the "sqltyping.py" good for?

[MartinThoma]

It seems not to be used anywhere.

$ grep -rnI "sqltyping" *
setup.py:53:      py_modules=['sqlmypy', 'sqltyping'],

It is a placeholder for introduction of mypy plugin specific types. It may be needed for something like https://github.com/dropbox/sqlalchemy-stubs/issues/9
