# 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.

For imports at least, configuration files offer some customization, though this might just generally be useful. (especially if mypy gets proper error codes).
