Hi all,

I have a class:

template<typename function_type>
class function_vector {
private:
   std::vector<boost::function<function_type> > functions;
};

I want to write an operator() for this template class that takes all the
arguments necessary to invoke a function of type function_type.  When
called, it should call each function in the functions field.

How do I do this?

I think Boost.Signals2 does something like this, but I can't work out how it
is done.

Cheers,

-John
