Okay, and? I didn't make the claim that some other language was all that. I was dispelling the claim that Python is.

Well, we've so far been restricted to function names which is what the claim was. There are plenty of cryptic other names in Python like ABCMeta, deriving from `object`, MRO, slots, dir, spec, etc.
The idea you can't do RAD with libraries is insane. Games are developed rapidly, and a lot of game engines use C#. The fact that you're using Unity, a very large dependency, means nothing regarding whether you can do RAD, which is more about having the right architecture, tooling, and development cycle.
