The result_of protocol. Apart from phoenix::function, the frontend API 
didn't change, phoenix::function now only recognizes Function objects 
conforming to the result_of protocol.

The interoperability is fully given, all tests from the bind testsuite pass.

None of these techniques were implemented.

This is documented.

Unified palceholders are documented. Interoperability with other Proto-based 
DSELs comes naturally with the use of proto.

This is probably the weakest part of Phoenix V3 at the moment. Compile times 
are slightly higher than with Phoenix V2. Keep in mind though, that Phoenix 
V3 is, due to proto, able to do more. More features come at a price.
