Hmmm, well adt_attribute_proxy only happens, erm with proxies. So I guess the
more relevant question is, how do you easily detect if at_c or any iterator
function returns a proxy(?). Alas, there's no easy way at the moment. It's
easy to add one and perhaps that might be a good idea. Please file a ticket
and I'll see what I can do.
