Description
The macro BOOST_PROTO_DECLTYPE_ only works once per scope because the variable "sz" does not embed the desired type name.

While an implementation detail, I find that it is quite practical to have decltype emulation through Boost.Typeof (which unfortunately is not able to leverage decltype itself) when decltype is not available on the target compiler.
Maybe it could be worth moving that out of Proto.

Note that this is an internal macro and shouldn't be used outside of Proto's implementation. But fixing this is simple enough, so I'll do it.
