Should I add a subscription system for discord events?

[Column01]

Hey Everyone!

I've been thinking recently of ways I could improve the modularity of the bot and I had the idea to add a system to subscribe to discord events. The events would likely cover most (if not all) of the events outlined in the API reference for discord.py. It would likely be similar to the commands registry, events could be loaded from a folder (event_handlers? events?) where it registers itself and the event it wants to subscribe to.

I might end up using a dynamic system where the event handler uses the event function name (on_connect, on_disconnect, etc.) and it uses a "Monkey Patch" to dynamically add a client event handler for that event, but that raises the question: What if you want multiple handlers listening to the same event? This proves to be an interesting challenge and I'm not sure how viable it is to complete without significant effort on my part.

Event registry example

An example for adding an event handler function dynamically would be the following

import types


class A:
    """ This would be the discord client class in bot.py"""
    def __init__(self):
        self.a = "a"
        self.message = None


def test_method(self, message):
    """ This would be the event method that would be registered, it would of course have the proper variables required (message, channel, etc.) """
    print("Testing 123")
    print("Class variable: " + self.a)
    self.message = message

# Bot instance
a = A()

""" This is how the method is registered to the bot class at runtime, this would be handled by the event registry so no user should need to do it. """
a.test_method = types.MethodType(test_method, a)
print(a.message) # Prints "None"

""" This is the event getting called """
a.test_method("A Message")
print(a.message) # Prints "A Message" from above

In conclusion

What do you think? Should I add a system like this where users can register custom event handlers? Does anyone have suggestions for code to implement something like this?

Update

I've started work on a system to do it, you can see it on this branch and try it for yourself if you like

Update 2

Finalized the documentation today and added it with #8 today. Please make an issue report if you see any issues with events!
