Hi,

I propose the following alternative approach:

* establish a restricted whitelist of global functions for which the performance gain would be
noteworthy if there wasn’t any need to look at local scope first;

* for those functions, disallow to define a function of same name in any namespace, e.g.: https://3v4l.org/RKnZt

That way, those functions could be optimised, but the current semantics of namespace lookup would
remain unchanged.
