Dylan DPC 9dbc9ed870 Rollup merge of #77514 - scottmcm:less-once-chain-once, r=estebank ... Replace some once(x).chain(once(y)) with [x, y] IntoIter Now that we have by-value array iterators that are [already used](25c8c53dd9/compiler/rustc_hir/src/def.rs (L305-L307))... For example, ```diff - once(self.type_ns).chain(once(self.value_ns)).chain(once(self.macro_ns)).filter_map(|it| it) + IntoIter::new([self.type_ns, self.value_ns, self.macro_ns]).filter_map(|it| it) ```		2020-10-05 02:29:42 +02:00
