I removed these comments because they're misleading. typing.re.Pattern is available in 3.5-3.7. It's been removed from the documentation as of 3.6, but it continues to be available. As of 3.6, the documented method is to use typing.Pattern, which also works in 3.5. I've adopted that pattern in this PR, which corrected the mypy error

if PY36:
import typing
re_type = typing.re.Pattern
else:
re_type = type(re.compile(''))
re_type = Pattern
