Why are you guys stuck on 's' definitely being a string? It could just as easily be a struct or anything else imaginable, in which case, you're back to not knowing anything about it from the name 's' without going to look it up. You can contrive simple examples about basic data types all you want, the simple cases and built in types are precisely where it's not a problem. Go read the src for Go's Unicode package as an example, you get 60 line methods with stuff like 't1' used all over the place and the value of t1 is assigned pages away from where it's actually used.
