mypy.bogus_type

A Bogus[T] type alias for marking when we subvert the type system We need this for compiling with mypyc, which inserts runtime typechecks that cause problems when we subvert the type system. So when compiling with mypyc, we turn those places into Any, while keeping the types around for normal typechecks. Since this causes the runtime types to be Any, this is best used in places where efficient access to properties is not important. For those cases some other technique should be used.
