This idea has a lot of merit, as does the option of not giving them a top-level name at all e.g. they could be String.Slice or String.SubSequence. It would underscore that they really aren’t meant to be used except as the result of a slicing operation or to efficiently pass a slice. OTOH, Substring is a term of art so can help with clarity.
