matejcik f0d6539d3d feat: custom Pylint plugin 
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):

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:

async def show_foo() -> None:
    return await show_something("foo")

# ... or ...

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