If you want your channels to have type in_channel or out_channel, and
be usable with the I/O functions provided by the standard library,
then this is not possible with the current implementation.

However, it is easy to define your own types my_in_channel, my_out_channel
that wrap the system channel types, as well as your own channels, and
provide operations that dispatch on the channel kind, either using
variant types, records of functions, or objects.
