Description
mypy 0.761; python 3.7.6
Defining a Tuple type on multiple lines causes a few lines to render Red with the HTML report:
from typing import TypeVar, Tuple, Optional
Result = TypeVar("Result")
WorkerResult = Tuple[
Optional[Result], # <- "No Anys on this line!"
Optional[BaseException], # <- "No Anys on this line!"
str # <- "No Anys on this line!"
]
whereas this is all green:
WorkerResult = Tuple[Optional[Result], Optional[BaseException], str]
