 You can't have a trait implementation exist in one edition and not in another,
 since editions can be mixed.

+Instead, we decided to add the trait implementation in *all* editions (starting in Rust 1.53.0),
 but add a small hack to avoid breakage until Rust 2021.
 In Rust 2015 and 2018 code, the compiler will still resolve `array.into_iter()`
 to `(&array).into_iter()` like before, as if the trait implementation does not exist.
 This *only* applies to the `.into_iter()` method call syntax.
-It does not affect any other syntax such as `for e in [1, 2, 3]` or `iter.zip([1, 2, 3])`.
+It does not affect any other syntax such as `for e in [1, 2, 3]`, `iter.zip([1, 2, 3])` or
+`IntoIterator::into_iter([1, 2, 3])`.
 Those will start to work in *all* editions.
 
 While it's a shame that this required a small hack to avoid breakage,
 we're very happy with how this solution keeps the difference between
 the editions to an absolute minimum.
+Since the hack is only present in the older editions,
+there is no added complexity in the new edition.

 we've decided to reserve syntax for prefixed identifiers and literals:
 `prefix#identifier`, `prefix"string"`, `prefix'c'`, and `prefix#123`,

 This is a breaking change, since macros can currently accept `hello"world"`,
 which they will see as two separate tokens: `hello` and `"world"`.
