The "Operator Overloading" page of the spec says that:

   "...the following parameter signatures for opAssign
    are not allowed:
    ...
    opAssign(T)
    ...
    where T is the same type as the aggregate type A..."


However, the following compiles:

    import std.stdio;

    struct S
    {
        S opAssign(T)(T t)
        {
            writeln(T.stringof);
            return this;
        }
    }

    void main()
    {
        S a, b;
        a = b;
    }

When run, it prints 'S'.
