override as possible keywords.
We intend to add some mechanism to Rust to support more efficient inheritance
(see, e.g., RFC PRs #245 and #250, and this
on discuss). Although we have not decided how to do this, we do know that we
will. Any implementation is likely to make use of keywords
used, to remain reserved),
override, so it makes
sense to reserve these now to make the eventual implementation as backwards
compatible as possible.
override reserved keywords.
Takes a few more words out of the possible vocabulary of Rust programmers.
Don't do this and deal with it when we have an implementation. This would mean bumping the language version, probably.
