good alternative, I already forgot about the power of structs

It would be a very good solution if we can init a struct using
its named field. Something like:
struct S
{
int a;
int b;
int c;
}
S test = { a:1, b:4; };
So:
void myFunc(S param); => myFunc({a:1, b:3});
I know: you say that this has trouble with overloading:
void myFunc(S param);
void myFunc(T param);
But the same goes for this:
void f(float i) { writeln("float"); }
void f(double i) { writeln("double"); }
f(1);
And simply it won't compile. (for template arguments too)
You can solve this doing: f(1.0f); or f(1.0);
In the same way you can solve first problem calling:
myFunc({a:1, b:3}.to!S) or myFunc(S{a:1, b:3}) or
myFunc(cast(S){a:1, b:3}) or some other exotic syntax you want
add to language, if needed (rarely, i guess).
And the same goes for:
auto blah = {a:1, b:2};
