The SliceConcatExt trait offers methods
concatandjoinon slices. For somewhat technical reasons, it wasn't possible to make these inherent methods.The methods themselves are stable, but the trait isn't. However, since the trait is in the prelude, the methods are usable in stable today.
Ideally, the methods would also be available on iterators, but there are performance ramifications for doing so. Impl specialization may help.
