pytype: import typing directly...
pytype: import typing directly First we no longer needs the pycompat layer, second having the types imported in all case will allow to use them more directly in type annotation, something important to upgrade the old "type comment" to proper type annotation. A lot a stupid assert are needed to keep pyflakes happy. We should be able to remove most of them once the type comment have been upgraded.
