I have some signal, with potential callables connected to it.
When I emit it, I want to wait for each callback to return before pursuing.
Something like:

await emit_signal('my_sig')

But it return immediatly after launching the callbacks execution.

Complete example:

extends Node

signal sig()

func _ready():
    await emit_signal('sig')
    print('emitted !')

func _on_sig():
    await get_tree().create_timer(1).timeout
    print('sig waited')

Is it possible using GDScript signal's implementation, or should I implement my own Publisher-Subscriber ?
