Hmm, this actually doesn't seem to be resolving my issue. I'm 
still getting the error about not being able to expand x.

I tried it like below and got the same error.

auto bar(T...)(T x)
{
        static if (T.length > 1)
        {
                return foo(x);
        }
        else static if (T.length == 1 && isTuple!(T))
        {
                return foo(x.expand);
        }
}
