Every time function autoloading been brought up in the past, there have been concerns about performance issues when calling a global function from inside a namespace. E.g. calling `strlen` in a loop would become far slower if every call has to trigger the autoloader.
This trick for perf improvement is overblown. It's misconception that it does provide speed advantage for most functions and reasons behind it. It does so only for those implemented as opcodes. People started to abuse it by importing ALL functions. Such overzealous approach completely prevents useful things like function mocking.
