- Szu-Wen said

- It's a joke, lighten up ;).
-

- (referring to his comment about portability of behavior)
-
- Actually the joke is on you, because the comment you made is not a joke
- at all but instead a very important point, around which a lot of language
- design decisions focus.
-
- An obvous goal of any language design is to minimize or eliminate
- undefined and non-deterministic behavior.
-
- These goals are often not net because of two important considerations:
-
- 1. Over specifying can lead to inefficient code (e.g. requiring left to
- right evaluation)
-
- 2. Some features (low level bit twiddling, tasking, etc.) may make it
- desirable semantically to introduce undefined or ND behavior.
-
- Debating the compromises here is a major activity of language design.
