Add `// run-pass` annotations to all the tests under `ui/run-pass/`. (I may have accidentally added it to some auxilliary crates as well; my emacs-macro-based methodology was pretty crude.) 2018-08-30 12:18:55 +00:00			`// run-pass`

Allow writing types which "can't" be instantiated. The borrow checker doesn't allow constructing such a type at runtime using safe code, but there isn't any reason to ban them in the type checker. Included in this commit is an example of a neat static doubly-linked list. Feature-gated under the static_recursion gate to be on the safe side, but there are unlikely to be any reasons this shouldn't be turned on by default. 2015-06-28 17:38:28 +00:00			`pub fn main() {}`
