In experimenting with the macro, I have hit what I believe is either a bug in GCC or what I would consider a huge failing of C++0x trailing return types (someone please aid me in figuring this out). One of the main reasons why trailing return types are helpful is that the arguments to the function or function template you are writing are able to be refered to when forming the return type, however, when dealing with non-static member functions, it seems to me that you are not able to refer to "this" or non-static members. This is definitely a bug somewhere.
Specifically, it is a bug in GCC, because the standard says in [basic.lookup.unqual]p8: "A name used in the definition of a member function of class X following the function's declarator-id [....] shall be declared in one of the following ways: [...] - shall be a member of class X or be a member of a base class of X [...]" The trailing return type in a member function definition is part of the definition and is after the declarator-id, so the paragraph applies. Furthermore, the lookup rules don't make a distinction between different kinds of members. Sebastian
