Method wrap_context

mypy/build.py:3064–3093

Temporarily change the error import context to match this state. Also report an internal error if an unexpected exception was raised and raise an exception on a blocking error, unless check_blockers is False. Skipping blocking error reporting is used in the semantic

(self, check_blockers: bool = True)
