Hi,

I watched the C++Now session about Proto v5, and now I want to play with 
it. I do not have the luxury of a Clang build from trunk, but I do have 
GCC 4.8.1 which should do pretty well.

I cloned the repository at https://github.com/ericniebler/proto-0x/. 
After jumping a few hoops, I am now left with tons of instances of the 
same errors:

- error: no type named 'proto_grammar_type' in ...
          using type = typename Ret::proto_grammar_type(Args...);

- error: no type named 'proto_action_type' in ...
          using type = typename Ret::proto_action_type(Args...);

For at least some cases, those are clear errors since the Ret type 
represents an empty structs (e.g. `not_`).

What is going on? What should I be doing to get Proto v5 to compile?

Regards,
