Yes. I left it as the last one because probably will be unsuccessful to find a template only way to expand overoload_functions(s) without repetition, and without preprocessor macros.
For the very few I know boost, the code I've looked at in the libraries it seems that in this cases the accepted way is to rely on preprocessor.
But for my untrained eye is still difficult to read such a code. And for my untrained sense of aesthetic I would call that code a little bit on the ugly side. I, perhaps strange enough, still prefer to see the whole set of repetitions instead of one packed BOOST macro stuff block.
Ok, your call, since you're the one taking the challenge anyway :) Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
