Re: opDispatch and compile time parameters

[Jack Applegame via Digitalmars-d]

D template system is very powerful.  This is more generic 
solution:

import std.stdio;
class B {
    auto p1(T)(T arg) { writeln( "p1: ", arg ); }
    auto p2(T, int C)(T s) { writeln( "p2: ", s, " / ", C); }
}
class C(T) {
    T b = new T;
    template opDispatch(string s) {
        template opDispatch(TARGS...) {
            auto opDispatch(ARGS...)(ARGS args) {
                static if(TARGS.length) return mixin("b." ~ s ~ 
"!TARGS(args)");
                else return mixin("b." ~ s ~ "(args)");
            }
        }
    }
}
void main() {
    auto b = new C!(B)();
    b.p1("abc");
    b.p2!(int, 10)(5);
}
