# type: ignore[import] at top of file causes all error codes to be ignored #11999
Description
Windows 7, Mypy 0.931, Python 3.8.10
An # type: ignore[import] line at top of file causes all error codes to be ignored, not just that error code.
I'm guessing this was never supposed to work, and is just a side effect of #964. However, (1) this is too confusing and easy-to-miss, (2) this feature would be very useful in my opinion. Sometimes there's just this one error that comes up lots of times in a file and I want to shush just that one without losing the other warnings.
