> The Godot documentation claims that GDScript has all sorts of advantages over using other scripting languages that sound qualitatively superior, but it lacks quantitative comparisons.

The advantage of GDScript is that all its primitives are the same as the C++ primitives that lie underneath. It's memory management model is the same as the engine's, etc... A GDScript function is a C++ function. GDScript is completely integrated into the engine, so if you're doing typical game-dev sort of things, there's literally no overhead.
