Juse use the documented API, C++ didn't remove functions and pointers from
the language :)

instantiate:

  struct ev_loop *loop = ev_loop (0);

you pass that loop ro the ev::io constructor by using one of the documented
ways to do that:

  constructor: ev_io my_io (loop);
  using set:   my_io.set (loop);

Passing tp to the constructor is preferable, as otherwise you will have a
temporary binding to the default loop.

You can also use the rest of the documented API in C++, the watcher
classes are just added sugar, they are not required to use libev.

As for the undocumented loop classes, these are undocumented for a reason
(they have never been finished, or even tested). You are invited to use
them if you wish, but if it breaks, it's yours to keep :)
