[zeromq-dev] Question about python binding generator

[Joe McIlvain]

The reason that method is static/singleton (which in this case, we use
interchangably) is because the "self" argument does not have to be an
instance of `zsock_t` (it could also be a libzmq socket pointer already).
Essentially, the "self" argument can be any arbitrary object as far as the
bindings are concerned, and the return value is either a valid libzmq
socket pointer or NULL.

So, it can't use the python "self" as the self argument, because then you
couldn't pass in an arbitrary argument as the "self".
