 ### `const` value repetition for arrays
 
 Arrays in Rust can be written either as a list `[a, b, c]` or a repetition `[x; N]`.
-For lengths `N` greater than one, repetition has only been allowed for `Copy`
-types, and [RFC 2203] sought to allow any `const` expression there. However,

+and [RFC 2203] sought to allow any `const` expression there. However,
 while that feature was unstable for arbitrary expressions, its implementation
 since Rust 1.38 accidentally allowed stable use of `const` _values_ in array
 repetition.
