I like having clear() to mean clear all. And having empty() to mean all
overloads are empty. For signature-based clear() and empty(), one would use
get<signature>().empty() and get<signature>.clear().

But then, it is just me.

Also, I've skimmed thru the implementation. It looks like that each
signature is managed by an auto_ptr to a boost::function. How about
"small-overload optimization" in that the boost::function objects for the
first couple of signatures are stack-based (ideally based on the dynamic
order of callables being set, which is not necessarily the same as the
static order of signatures in the mpl sequence of signatures.)
