Explicit name mangling for function overrides

char * stringify~for_int (int x);
char * stringify~for_char (char c);

// The compiler can infer the suffix to use
stringify (1); // Same as stringify~for_int (1)
char * (*ptr)(int x) = stringify~for_int (1); // It can be given explicitly to get an exact function
