rustc: Prevent repeated moves out of proc upvars This fixes the categorization of the upvars of procs (represented internally as once fns) to consider usage to require a loan. In doing so, upvars are no longer allowed to be moved out of repeatedly in loops and such. Closes #10398 Closes #12041 Closes #12127 2014-04-08 23:59:18 +00:00			`fn main() {`
Remove even more box syntax uses from src/test Prior work, notably 6550021124451628b1efc60c59284465b109e3aa from #88316 has removed box syntax from most of the testsuite. However, some tests were left out. This commit removes box_syntax uses from more locations in src/test. Some tests that are very box syntax specific are not being migrated. 2022-07-07 02:36:10 +00:00			`let x: Box<_> = Box::new(1);`
