The following code simply hangs DMD 2.048.  I haven't the slightest clue why.

struct Foo(Args...) if(Args.length > 1)
{
    Args args;
}

template Foo(Arg)
{
    alias Arg Foo;
}

Foo!(Args) getFoo(Args...)(Args args)
{
    static if(Args.length > 1)
    {
        return Foo!(Args)(args);
    }
    else
    {
        return args[0];
    }
}

Foo!(Args) getFoo(Args...)(Args args, uint num)
{
    static if(Args.length > 1)
    {
        return Foo!(Args)(args);
    }
    else
    {
        return args[0];
    }
}

void main()
{
    getFoo(1);
}
