These are breaking changes to PR #66.
* Remove are_tagged_arguments_mp11 and is_argument_pack_mp11. They were reviewed as redundant.
* Remove MP11 support for ArgumentPack models for now. (This feature relied on templates that were not supposed to be specialized.)
* Add are_tagged_arguments_mp11 and is_argument_pack_mp11 metafunctions when Boost.MP11 is usable.
* Predicate requirements can be encoded as Boost.MP11-style quoted metafunctions as well as by MPL binary metafunction classes.
* Argument packs qualify as Boost.MP11-style lists as well as MPL sequences.
* Internal components and test programs use Boost.MP11 and C++11 type traits vice MPL and Boost.TypeTraits when Boost.MP11 is usable.
* Add "test/literate/parameter-enabled-function-call-operators0.cpp" to test suite under alias 'parameter_literate_tests'.
* Add compose() test routine to "test/compose.cpp"
* Replace LIBS_PARAMETER_TEST_COMPILE_FAILURE_MSVC with LIBS_PARAMETER_TEST_COMPILE_FAILURE_VENDOR_SPECIFIC in case compilers other than MSVC start exhibiting errant behavior.
* Adjust for the fact that BOOST_PARAMETER_MAX_ARITY is defined regardless of whether or not BOOST_PARAMETER_HAS_PERFECT_FORWARDING is defined.
* Use minimal file headers to #include vice <boost/parameter.hpp>.
* Normalize license wording.
* Add statements to #include header files that directly define components used in this test.
* Qualify by namespace vice using declarations.
Decouple the compose() function and the BOOST_PARAMETER_NO_SPEC_* code generation macros from BOOST_PARAMETER_MAX_ARITY for older compilers so their generated functions can take in more arguments.
* Add variadic metafunction boost::parameter::are_tagged_arguments to help improve overload resolution capabilities. Used by compose() and the new BOOST_PARAMETER_NO_SPEC_* code generation macros.
* Add variadic function template compose() which takes in named arguments and returns them in an argument pack.
* Add code generation macros BOOST_PARAMETER_BASIC_FUNCTION_CALL_OPERATOR, BOOST_PARAMETER_BASIC_CONST_FUNCTION_CALL_OPERATOR, BOOST_PARAMETER_NO_SPEC_FUNCTION, BOOST_PARAMETER_NO_SPEC_MEMBER_FUNCTION, BOOST_PARAMETER_NO_SPEC_CONST_MEMBER_FUNCTION, BOOST_PARAMETER_NO_SPEC_FUNCTION_CALL_OPERATOR, BOOST_PARAMETER_NO_SPEC_CONST_FUNCTION_CALL_OPERATOR, BOOST_PARAMETER_NO_SPEC_CONSTRUCTOR, and BOOST_PARAMETER_NO_SPEC_NO_BASE_CONSTRUCTOR.
* Fix compiler error: base `boost::reference_wrapper<int>' with only non-default constructor in class without a constructor.
* Ignore normalized_argument_types test failures.
<boost/parameter/config.hpp>
* Introduce configuration macros BOOST_PARAMETER_CAN_USE_MP11 and BOOST_PARAMETER_DISABLE_MP11 usage.
* Update perfect forwarding support requirements to fix regressions on test matrix.
<boost/parameter/parameters.hpp>
* Allow mp11::mp_list to be default parameter_spec type if available.
