The term you are looking for I think, is "aliasing"

nothing is shadowed, here, the builtin is just assigned to another name in the current scope, that's all.

I think shadowing a built-in generally refers to asigning a built-in to something else, e.g. print = lambda x:x+1

Note that you should optimize your code as tests can go up to 10 million (JS) && 100 million (python).
