There's plenty of that in the regex internal API and data structures,
too: it has been the written with the 'everything is a char pointer
and characters are bytes' mindset which now stings us in various
painful ways: passing char pointers and (explicit) byte lengths
instead of SVs and (implicit) character lengths, for example.
