tests: Add missing run-pass annotations 2019-07-27 00:54:25 +03:00			`// run-pass`

fallout: run-pass tests that use box. (many could be ported to `Box::new` instead in the future.) 2015-01-08 02:25:56 +01:00			`#![feature(box_syntax)]`
Reformat source tree (minus a couple tests that are still grumpy). 2011-06-15 11:19:50 -07:00
test: De-`@mut` the test suite 2013-12-31 15:46:27 -08:00			`use std::cell::Cell;`

Add `: Box<_>` or `::Box<_>` type annotations to various places. This is the kind of change that one is expected to need to make to accommodate overloaded-`box`. ---- Note that this is not all of the changes necessary to accommodate Issue 22181. It is merely the subset of those cases where there was already a let-binding in place that made it easy to add the necesasry type ascription. (For unnamed intermediate `Box` values, one must go down a different route; `Box::new` is the option that maximizes portability, but has potential inefficiency depending on whether the call is inlined.) ---- There is one place worth note, `run-pass/coerce-match.rs`, where I used an ugly form of `Box<_>` type ascription where I would have preferred to use `Box::new` to accommodate overloaded-`box`. I deliberately did not use `Box::new` here, because that is already done in coerce-match-calls.rs. ---- Precursor for overloaded-`box` and placement-`in`; see Issue 22181. 2015-02-17 21:41:32 +01:00			`let x: Box<_> = box Cell::new(5);`
