No. You can unpack arguments, but you can't choose signal2
or signal3 and so on.

I meant a bit another thing.

//From your examples:
typedef void my_function(int);

typedef function_type_signature<my_function> my_signature;

typedef mpl::push_back<my_signature,float>::type my_modified_signature;

boost::signal<my_modified_signature::representee>. == boost::signal<void (int, 
float)>
//You can't do the same for signalN!!!!!
