Hi Jens,

Try attribute_proxy::type. It's documented here: http://www.boost.org/doc/libs/1_50_0/libs/fusion/doc/html/fusion/notes.html#...

Hi Joel,

great!

Is there a generic way to detect which sort of Adapted struct it is? typename fusion::result_of::at_c::type::type t; Will probably only work for proxies, which would be fine for my code.

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.
