Wouldn't it be possible to use something like the constructor<>
template to generate signatures? For example:

struct hello {
  //..
  int foo(int i, bool b = false);
};

py_hello.def(boost::python::signature<int>, &hello::foo, "foo");
py_hello.def(boost::python::signature<int, bool>, &hello::foo, "foo");

Doesn't this look like something that would be easy to implement?
