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

Move replace and swap to std::mem. Get rid of std::util Also move Void to std::any, move drop to std::mem and reexport in prelude. 2014-02-01 04:35:36 +08:00			`use std::mem::swap;`
Stop using the '<->' operator 2013-05-06 00:42:54 -04:00
