Think of it like this:
There is object-oriented message passing (using message passing to
handle object orientation), which is what ObjC and Smalltalk use as
paradigms to describe how they work.
Then there is the asynchronous message passing, which involves queues
of messages that are polled, etc.
If your language has a stack datatype, it has a queue datatype. If it
has these, it can do asynchronous message passing.
On the other hand, no one in the Python world really describes
instance.method() as passing a message to 'instance' with the value of
