2911	shared_from_this free function	fhess	Frank Mori Hess	"Attached is an implementation of a free shared_from_this function, plus a non-template enable_shared_from_this_base class which can only be used with the free shared_from_this function.  The free function will also work with the usual enable_shared_from_this template.  It is implemented on top of the existing enable_shared_from_this class, and so requires no modification of the existing smart_ptr code.

This scheme has the advantage of simplicity, since the ""curiously recurring template pattern"" is not needed.  It also ""just works"" if you have a class hierarchy that looks like ""X is derived from Y is derived from enable_shared_from_this_base"" and want to use shared_from_this with both X and Y.

I've only tried it with gcc 4.3.
