Of course ;-) “Pleasant to use” is not my primary need here. > You'll see that when I've posted my Python-based monads essay... The reason I would like this essay is that I want to teach the notion of first-classing of computation, if possible without the learning curve of Haskell syntax, type-system etc There is a well-known joke in the Haskell space that “Haskell is an excellent imperative language” I guess this is because monads can first-class arbitrary imperative (computational) notions. Since in python the two worlds of purely functional and imperative meet being able to see this in python would be neat! - Anuradha -- https://mail.python.org/mailman/listinfo/python-list
