I haven't taken the time to look at your project yet either, but
thanks for reminding the list that it's available in the sandbox. I
have to say that I don't find the idea of gutting the current
implementation to be particularly attractive. Boost.Function is
already proven and familiar, and there's more we can still do with it.
Plus, it takes time to study a lot of new code.
