Ian Jackson 274e2993cb Stablize slice::strip_prefix and strip_suffix, with SlicePattern ... We hope later to extend `core::str::Pattern` to slices too, perhaps as part of stabilising that. We want to minimise the amount of type inference breakage when we do that, so we don't want to stabilise strip_prefix and strip_suffix taking a simple `&[T]`. @KodrAus suggested the approach of introducing a new perma-unstable trait, which reduces this future inference break risk. I found it necessary to make two impls of this trait, as the unsize coercion don't apply when hunting for trait implementations. Since SlicePattern's only method returns a reference, and the whole trait is just a wrapper for slices, I made the trait type be the non-reference type [T] or [T;N] rather than the reference. Otherwise the trait would have a lifetime parameter. I marked both the no-op conversion functions `#[inline]`. I'm not sure if that is necessary but it seemed at the very least harmless.
