This has nothing to do with my original problem, but I'm curious what this
Boost.Function constructor would look like if there was a working
boost::arity_traits class. I'm relatively new to generic programming using
C++ templates and I'd like to learn more.

Thanks in advance for teaching me a new trick. :)
