[C++-sig] wrapping the PyObject_Call() interface

Thanks that works fine.

Though I'd like to ask you whether there is any reason for unary operator *
to work only with boost::python::tuple and not with boost::python::list. At
first I used the latter and I got a python exception that while the
functions I was calling was requiring N arguments, it was provided with 0.
It was also the case of a bound member function, meaning that at least the
self argument was already embedded in the boost::python::object I was
calling. When I converted the list to a tuple the call run smoothly.

Is this patch going to be in the 1.36.0 release? If not are there any plans
for which release it will be included in?
