So you agree that it won't work.

BTW, it happens all the time when dealing with strings. For example, dealing 
with filenames, file extensions, and paths. Components can come from the command 
line, string literals, malloc, slices, etc., all mixed up together.

Overloading doesn't work because a string literal and a string allocated by 
something else have the same type.

My point is you can't avoid making the extra copies without GC in any reasonable 
way.
