No examples, sorry, but the idea is to provide a Builder instead of a
ByteString, so that you can cheaply concatenate together smaller
pieces and avoid a potentially costly length operation *if* you know
the ultimate size of the body. You could consider the following to be

    RequestBodyBS bs ~== RequstBodyBuilder (S.length bs) (fromByteString bs)
