Path the function definition from Godot when connecting signals

I'm thinking about possible workarounds on how the function definition can be passed from Godot to external editors when connecting signals in Godot in order to get the same behavior as with the built-in script editor.

I'm sure that I'm not the first one looking into this, so maybe someone can share their experience and I will start from there and see if I can come up with something.

And please let me know if there is a general consensus that it could not be possible at all, or without breaking something else.
