- Run: !
- evaluating code
E.g.,
B = <1 + 1> E = < .~B + .~B > = < (1 + 1) + (1 + 1) > -- at the tree level. R = !E = 4
Note: .~<T> = T, but only inside brackets. Outside
- Pure OOP
- SmallTalk, Objective-C, and Ruby came into this discussion.
Ruby allows “method missing” akin to Objective-C’s message passing; or Python’s “getAdder”.
