tests: Add missing run-pass annotations 2019-07-26 16:54:25 -05:00			`// 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. 2014-01-31 14:35:36 -06:00			`use std::mem::swap;`
Stop using the '<->' operator 2013-05-05 23:42:54 -05:00
