Use of self in _init() to reference variables in classes is apparently bad.

Someone said on the Godot discord channel that using self just to reference class variables isn't good practice, as it literally uses that reference to access the variables, as opposed to just accessing the variables it can already access.

or in other words, it goes:

set_variable
vs
access_reference(self).set_variable

I don't know whether this is actually true or not, so I think I'll just leave this open until I know more.
