New submission from Christoph Wruck:
Currently we have a split function which splits a str/bytestr into
chunks of their underlying data. This works great for the most tivial jobs.
But there is no possibility to pass an offset parameter into the split
function which indicates the next

Serhiy, you will be right if you've to split a complex string such spliting
strings with more than one separator. In this case I would prefer a regex bases
solution too. Otherwise we could actually use the re-lib for every of those
jobs without using the
