3) Declaring a packed struct in a function literal that gets
immediately called:
----
enum size_so_very_clever(Types ...) = () {
     struct S { align(1) Types fields; }
     return S.sizeof;
} ();
----

I'd just do:

        template sizeofStruct(Types...) {
                struct S { align(1) Types fields; }
                enum sizeofStruct = S.sizeof;
        }

Skip the CTFE implied by the function literal, the compiler already
knows the size very well.

Yup. That's better.
