librustc: Remove cross borrowing from mutable `Box`es to `&mut`. This will break code like: fn f(x: &mut int) {} let mut a = box 1i; f(a); Change it to: fn f(x: &mut int) {} let mut a = box 1i; f(&mut *a); RFC 33; issue #10504. [breaking-change] 2014-06-25 06:11:57 +00:00

Remove box syntax from most places in src/test outside of the issues dir 2021-08-25 00:39:40 +00:00
