for now, it catches the following incorrect function:

async def show_foo() -> Awaitable[None]:
    return show_something_else("foo")

because to correctly show the result, the caller would have to "await (await show_foo())"

(this should either be "async def show_foo() -> None", or "def show_foo() -> Awaitable[None]")

# Custom Pylint rule checker
For now, it catches the following problem (`async-awaitable-return`):
```python
async def show_foo() -> Awaitable[None]:
return show_something("foo")
```
This is almost certainly a mistake -- the caller would need to say `await (await
show_foo())` to actually show the foo.
The function should be one of:
```python
async def show_foo() -> None:
return await show_something("foo")
# ... or ...
def show_foo() -> Awaitable[None]:
return show_something("foo")
```
