           Summary: std.utf.decode: index parameter should be able to pass
                    by value

Is it reasonable to pass everywhere when it's possible by *ref* to function
even integers? This goes to very stupid bugs. If ref is neded there (but I
think it is not) we could use *auto ref* instead for those cases where it's not
possible get address of parameter or something else.

The above example doesn't compiles because we can't get *ref* for 0 literal

import std.stdio, std.utf;

void main()
{
    string str = "チ";

    writeln(decode(str, 0));    

}
