Hi,

Consider the following task: Given a
-) pointer to a function, and
-) an iterator range with elements of type void *,
the function-ptr shall be called with all the elements in the range as 
arguments.

So conceptionally something like this:

template <typename Func, typename Iter>
void make_call(Func, Iter begin, Iter end)
{
int n = std::distance(begin, end);
(*Func) (*(begin), *(begin + 1), *(begin + 2), ..., *(begin + n - 1))
}

The interface (function declaration) here is +- what I want, the 
implementation shown of course is dummy-code not working. Does boost 
provide a more or less easy way to get this implementation smoothly 
done? C++ is 2003 version, so code must be compatible with e.g. VS 
2008.. Note that I would know in principle a way how to do implement it 
myself, which involves the creation of a separate class for each number 
of arguments, but that's precisely what I want to avoid and I hope that 
wheel has already been invented in some boost-library :)

thanks and regards,
Thomas
