This will never run:

```py3
@requireDarwin
@requireWindows
def test():
    ...
```

This will not run on Linux, because `@requireWindows` is not satisfied.
```py3
@requireNotDarwin
@requireWindows
def test():
    ...
```

For "require Darwin or Windows", you need:
```py3
@requirePlatform(["darwin", "windows"])
def test():
    ...
```

For "require Darwin on ARM64 or Windows on ARM64", you need:
```py3
@requireARM64
@requirePlatform(["darwin", "windows"])
def test():
    ...
```
