Extend the snake_case Feature to Signals?

The PySide feature snake_case changes the representation of PySide methods, only. This could be extended to include other names like signals, or even all names stored inside a class.

Motivation:
In PYSIDE-1730, I suddenly became aware that there are situations where a signal name is used as a function name. The signal builds a proxy for the function, although a signal was found.

Now consider a switch from normal to snake_case: Two objects with the same name could now become two objects with a different name, or vice-versa.

I fear a bit that people will discover this, and I think the situation becomes a bit insane. Therefore the proposal: Treat all lower-case names the same and rename everything, instead of just method names.

If that should be done: Do we need another feature for the transition? Or is it easier to extend the snake_case feature right away?
