This fixes the following case outlined in #824:

from subprocess import popen  # Module 'subprocess' has no attribute 'popen'

is now

from subprocess import popen  # Module 'subprocess' has no attribute 'popen'; maybe "Popen"?

Thanks! I have just couple formatting suggestions. Fix them and I will merge when tests pass in CI.

@marcodoordash There are still two failures in CI:

• You forgot to update the new semantic analyzer test output in one test.
• Self-type-check failed.
