In the same area, the class_ definition is like this (4 args):

template <class T
          , class Bases = bases<>
            , class HeldType = T
            , class NonCopyable = unspecified
  class class_ : ....

But the docs and examples of wrapping do this (Only 3 args):

class_<Base, BaseWrap, boost::noncopyable>("Base", no_init)

This is confusing.

I had a look at the header and see you do something I don't (yet) understand
to make this happen. Very cool.
