I'd be interested in comments on an introspection library I've been developing.

there has been no "Is there any interest..."-e-mail yet, as it was started out of necessity in "namespace detail" of another library, so you're also welcome to express interest/disinterest in a library like this, without any specific comments.

source code: https://svn.boost.org/trac/boost/browser/sandbox/intro/boost/intro/

the library defines a concept that exposes the members of a class, for introspection algorithms to work with.

Hi, Is it not what Boost.Fusion does already? The macro BOOST_FUSION_ADAPT_STRUCT looks very similar to your mapping: http://www.boost.org/doc/libs/1_43_0/libs/fusion/doc/html/fusion/adapted/ada... Regards, &rzej
