Here is an implementation of message-passing OO in Factor:
: create-message ( name -- word )
"->" swap append "messages" create ;
: MSG:
scan-word scan create-message
[ define-typecheck ] f ; parsing
Now you can write:
MSG: car move ... ;
MSG: window move ... ;
Which creates a generic word named ->move in the messages vocabulary.
I don't recommend using this, though.
