Is there a way to avoid the following combinatorial explosion of
overloaded functions when overloading for lvalue and rvalue
arguments? The following may be a bad example because int is
cheap to copy. So assume a large datatype instead of int.

yeah, sorry for not proposing a workaround: i thought that you already did
it, and now you're just interested why the original code doesn't work. ;-)
i think that this is a bug (or, rather, unimplemented feature).

I think the reason for the typeof problem is that it works with
expressions, not with types (so, typeof (int) is also not valid),

It's possible to maintain the sum as elements are added and removed.
Then, accessing it would be O(1).

No.
If you want to sum the elements you have to at-least look at
