This would require storing type information in a symbol, would it not? Either via mangling or some other method.

Yes. I proposed a method without mangling, but I suppose there isn't any reason why C couldn't use mangled names.
It also isn't a requirement that C++ use mangled names. Other ways of carrying the type information are possible. I like the idea of a reference to DWARF debug info, which C++ is already using to support stack unwinding for exceptions.

Overloading requires the type information to be part of the symbol "name" (ie, whatever is used for symbol lookup and linking) wether that is a mangled string or more complex data structure.
