First, thanks Eric for fixing incompatibility between Phoenix and
decltype-based result_of. This is really a great fix!

I ran Phoenix test-suite on
* clang 3.1, 3.2 (trunk)
* gcc 4.4-4.7, 4.8 (experimental)
with
* C++03, C++11 + BOOST_RESULT_OF_USE_DECLTYPE, C++11 + BOOST_RESULT_OF_USE_TR1

The only failure is lambda_tests.test (i.e. scope/lambda_tests.cpp)
on gcc 4.4-4.7 with C++11 + BOOST_RESULT_OF_USE_DECLTYPE.
Is this caused by deficiency of N3276 decltype support?

P.S. What was the main reason for the incompatibility between Phoenix and
decltype-based result_of? And how did you fix it?

Regards,
Michel
