Is there any clever way to move the method outside of a
templated block structure? Or is this as good as it gets.
I tried
// Explicit instantiation for 'int' type
//int add!(int, int);
void displayHexBoardData(HexBoard2!(float,uint) h); //
declaration
but that just returns
Error: declaration `displayHexBoard` is already defined

here
```d
import std.stdio;
struct Foo(T, L) { T t; L l; }
void display(T, L)(Foo!(T, L) f) { f.writeln; }
alias FooIntD = Foo!(int, double);
void main() { auto f = FooIntD(10, 20.3); f.display; }
