Consequently it shouldn't work if the import() is called in the same package, right? (Untested)

Hence the perldocs should be clearer:

> perlsub#Overriding-Built-in-Functions Overriding may be done only by importing the name from a module at compile time--ordinary predeclaration isn't good enough. 

A module is a .pm which supports importing with use It's normal practice to have its own package, but not necessarily so.
