But your interface only supports a subset of the slot types supported by 
Boost.Signals, since it doesn't support functor objects such as those 
returned by boost::bind.

However, your Signal class does highlight the fact that the boost signal0, 
signal1, ..., signalN classes might be implemented through a single variadic 
template class when compiling with a C++0x compiler.  This might reduce 
compile time overhead, since the compiler wouldn't have to generate and parse 
all the individual signalN classes.
