// We shouldn't need to rebind a moved upvar as mut if it's already
// marked as mut

pub fn main() {
    let mut x = 1;

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`

Remove integer suffixes where the types in compiled code are identical. 2015-03-03 08:42:26 +00:00			`let mut x = 1;`
Remove `Thunk` struct and `Invoke` trait; change `Thunk` to be an alias for `Box<FnBox()>`. I found the alias was still handy because it is shorter than the fully written type. This is a [breaking-change]: convert code using `Invoke` to use `FnBox`, which is usually pretty straight-forward. Code using thunk mostly works if you change `Thunk::new => Box::new` and `foo.invoke(arg)` to `foo(arg)`. 2015-04-01 15:12:30 +00:00			`let _thunk = Box::new(move\|\| { x = 2; });`
