[issue37398] contextlib.ContextDecorator decorating async functions

[Andrew Svetlov]

Andrew Svetlov <andrew.svetlov at gmail.com> added the comment:

Got you.

iscoroutinefunction() is not reliable: it detects async functions only but fails if we have a regular function that returns awaitable object.

I think AsyncContextDecorator is needed here to explicitly point that you want to wrap async function.

Another question is: sync or async context manager should be applied? I see use cases for both variants
