pytype crashes with syntax error on del statement about pytype HOT 2 CLOSED

So far, we have put an underscore in front of classes or types that are internal to a module. The advantage is that sometimes you do need to refer to an (internal) class of a module from a different pyi.

In the example of path.pyi, the internal type is a Union. Maybe we just shouldn't export union types from pyi, by default? Do we have any use cases where you'd actually want to declare a union in one pyi, but use it in another?

Typeshed's convention is still to prefix the names of typing constructs with an underscore; it's unlikely that pytype's parser will ever (intentionally) support del.
