[FIXED] Using a coroutine as decorator

Issue

in this scenario:

async def foo(f):
    async def wrapper(*args, **kwargs):
        return f(*args, **kwargs)
    return wrapper

@foo
async def boo(*args, **kwargs):
    pass

is the call to foo as a decorator for boo decorator an async call?

--First Edit: Also how does one handle calling chain of coroutines as decorators?

Solution

Thanks to @blacknght's comment, considering

def foo():
    def wrapper(func):
        @functools.wraps(func)
        async def wrapped(*args):
             # Some fancy foo stuff
            return await func(*args)
        return wrapped
    return wrapper

and

def boo():
    def wrapper(func):
        @functools.wraps(func)
        async def wrapped(*args):
            # Some fancy boo stuff
            return await func(*args)
        return wrapped
    return wrapper

as two decorators, and

@foo()
@boo()
async def work(*args):
    pass

As the foo is wrapping the work coroutine, the key is to await the func(*arg) in both decorators.
