Example:

import std.typetuple;

void packIt(Pack)(Pack p){ }  //3

void main()
{
    packIt!(int)(2); //7
}

Produces:
bug_alias.d(3): Error: module bug_alias std.typetuple.Pack(T...) is private
bug_alias.d(7): Error: template instance bug_alias.packIt!(int) error
instantiating

Used a recent dmd from github master HEAD.

Related code from std.typetuple:

private template Pack(T...)
{
    alias T tuple;

    // For convenience
    template equals(U...)
    {
        static if (T.length == U.length)
        {
            static if (T.length == 0)
                enum equals = true;
            else
                enum equals = isSame!(T[0], U[0]) &&
                    Pack!(T[1 .. $]).equals!(U[1 .. $]);
        }
        else
        {
            enum equals = false;
        }
    }
}
