Is this correct?

Yes. The justification for this is that otherwise foolib could silently 
hijack your main.d by introducing a new function "foo". If you want to 
overload against the library function, you can use an alias:

import std.stdio;
import foolib;
alias foo=foolib.foo;
void foo(const(char)[] s) { writefln("foo const"); }
void main(){
    foo("hello"); // foo string
}
