Sure, it *could* work but I doubt it ever actually will.

Instead, why not pass the type directly?

auto s = S!(typeof(x))(x);?

I know it's a little more work and not very pretty but it should 
solve the problem.

Or, if your constructors are simple enough, maybe something like 
this would work

struct S(alias X)
{
    this() { this.x = X; }
}

...

auto s = S!(x);
