# 1) Type[_T]
#   - Pros: Handles simple cases correctly
#   - Cons: Might produce less informative errors in the case of conflicting TypeVars
#   e.g. `attr.ib(default='bad', type=int)`
# 2) Callable[..., _T]
#   - Pros: Better error messages than #1 for conflicting TypeVars
#   - Cons: Terrible error messages for validator checks.
#   e.g. attr.ib(type=int, validator=validate_str)
#        -> error: Cannot infer function type argument
# 3) type (and do all of the work in the mypy plugin)
#   - Pros: Simple here, and we could customize the plugin with our own errors.
