It's easy enough to implement the guts.  What happened is that it
became clear I needed unnamed parameter support (like .def, where
parameters can come in any order) in order to implement a good
interface.  I started to look into extending the named parameters
library (http://article.gmane.org/gmane.comp.lib.boost.announce/54,
http://article.gmane.org/gmane.comp.lib.boost.announce/55) to support
unnamed parameters, and got stuck because I didn't understand the code
anymore (partly my own forgetfulness, partly the code itself).  Daniel
Wallin, the library's co-author was going to try to clear things up.
Since then, I'm not sure what's happened.
