This is because the Panda3D SDK was compiled with an older (ancient) version of xcode which used `-stdlib=libstdc++`, but newer versions only support `-stdlib=libc++`. You can either try to compile...

There definitely is a performance loss, but I don't know if I'd call it a large one. I made a test with 200 LUIButtons, plus a variable number of LUISprites....

I have a real-world example where this would be useful. In my case I have the data role which determines if the passed value should go into the _data dict....

I've applied the requested changes to the 3D code. I'll work on making the same feature in the 2D code.

Okay I've also gone ahead and implemented the same functionality into Area2D. I've updated my example project to include a 2D scene: [test_gravity_with_2d.zip](https://github.com/godotengine/godot/files/12024115/test_gravity_with_2d.zip)
