  // init<Ts...>(...) defines constructors.
  //
  // To add names to parameters, add an args() call as a parameter to
  // the init function call.
  //
  // To add a docstring to a constructor, pass it as the last parameter to the
  // init function call (as a string literal)
  //
  // One constructor can be called within the class_<>() function call. To have
  // multiple constructors, you use init<> together with .def() to append
  // others.
  //
  // If you want to add a docstring to the class as a whole, pass it as the
  // second parameter (*note:* not last if you want a constructor) to the
  // class_<>() function call
  //
  // def(...) defines functions and .def() defines member functions.
  //
  // To add names names to parameters, add an args() call as a parameter
  //
  // To add a docstring, pass a string literal as the last parameter to the
  // def/.def function call
  //
  // args(...) give names to parameters. This both adds the names to the
  // generated documentation and allows using python's named parameters
  //
  // .staticmethod("name") is required for any static member functions. Note
  // that things will compile without it but the function won't be callable from
  // python
  //
  // Enums need each value to be specified with the .value() function. Any enum
  // values specified before export_values() will be accessible directly from
  // the module while others will need fully qualified names (module.enum.value)
