Target components

action_server, actions

Description

i.e.: As something as:

@my_decorator
@action
def any_action(value: str) -> str:
    ...

is the same as:

def any_action(value: str) -> str:
    ...

any_action = action(any_action) # at this point we save the reference to the function, so, it doesn't work.
any_action = my_decorator(any_action)

and if it was inverted it'd be:

def any_action(value: str) -> str:
    ...

any_action = my_decorator(any_action) 
any_action = action(any_action) # The signature of the my_decorator won't be correct for introspecting.

Describe the solution you'd like to see

We could maybe make it work by not storing the reference and just storing the module/function name to get for calling but still introspecting on the given one (but it does have some caveats too).

Describe alternatives you've considered

Note: investigate if functools.wraps adds info on the wrapper so that the original one can be gotten for introspection.
