From my understanding of the new interface: boost::keyword is now boost::named_params::keyword, boost::keywords is now boost::named_params::parameters, and boost::named_param<KW,boost::mpl::true_,Restriction> and boost::named_param<KW,boost::mpl::true_,Restriction> are replaced by boost::named_params::required<KW,Restriction> and boost::named_params::optional<KW,Restriction>. Am I correct?

Yes, that's correct. Although the code has been moved to the Boost CVS and the namespace has been changed to 'parameter'.

The type-extraction functionality I mentioned earlier has now been reimplemented in terms of the current code base, as is the BOOST_NAMED_PARAMS_MEMBER_FUN macro I proposed a while back.

I also discovered an extraneous #define in <boost/named_params/aux_/arg_list.hpp> that prevents me from increasing the maximum arity of a function.

The files I added and/or fixed are in the new File Vault, subdirectory "expaler", filename "named_params.zip".

Thank you. I've merged your macro change into the trunk, but I'm holding off the type-extraction code until we have completed the changes we are currently working on. -- Daniel Wallin
