Version: 3.04
OS: Mac OS X 10.1.5
Submission from: 17.255.97.138 (17.255.97.138)
Consider the following two class types:
class type mule = object('a) method m: 'a -> 'a end
class type unicorn = object inherit mule method n: unit end
Since mule has a method where the object type is in a contra-variant
position, unicorn adds a method that isn't private, this means that
unicorn is not a subtype of mule.
I'd like to see the compiler generate a warning when this happens.
