confusing type error when using overloads

Bug Report

when using overloads, the type errors for mistakes are confusingly hidden

Expected Behavior

main.py:65: error: Argument 1 to "parse_success" has incompatible type "Tuple[CompletedProcess[str]]"; expected "CompletedProcess[str]"  [arg-type]
main.py:68: error: Argument 1 to "parse_other" has incompatible type "Tuple[CompletedProcess[str]]"; expected "CompletedProcess[str]"  [arg-type]
Found 2 errors in 1 file (checked 1 source file)

Actual Behavior

main.py:65: error: No overload variant of "parse_success" matches argument types "Tuple[CompletedProcess[str]]", "Callable[[str], Optional[int]]", "str"  [call-overload]
main.py:65: note: Possible overload variants:
main.py:65: note:     def [PARSE_RESULT] parse_success(res: CompletedProcess[str], *, parse: Callable[[str], PARSE_RESULT], default: None = ..., error_msg: Optional[str] = ...) -> Optional[PARSE_RESULT]
main.py:65: note:     def [PARSE_RESULT, T] parse_success(res: CompletedProcess[str], *, parse: Callable[[str], PARSE_RESULT], default: T, error_msg: Optional[str] = ...) -> Union[PARSE_RESULT, T]
main.py:68: error: Argument 1 to "parse_other" has incompatible type "Tuple[CompletedProcess[str]]"; expected "CompletedProcess[str]"  [arg-type]
Found 2 errors in 1 file (checked 1 source file)

Your Environment

replicated this in the playground on 1.1.1

Beginne damit, die verlinkte mypy-play-Reproduktion auszuführen, und vergleiche den Overload-Aufruf in main.py in Zeile 65 mit parse_other in Zeile 68. Verfolge, wie die Overload-Auflösung Diagnosen auswählt; abgeschlossen ist die Aufgabe, wenn das falsche Argument mit der direkten Meldung zum inkompatiblen Typ gemeldet wird und zugleich nützliche Overload-Fehler bei echten Nichtübereinstimmungen erhalten bleiben.
