   yeah, if needed we can provide a public splitting function. I though
about this a bit more and I think the current API is better because one
doesn't need to make deallocation of object as the result of calling this
function, all string returned are comming directly from the regexp. If
we split one will need to deallocate the chunks produced because they
possibly don't exist in the regexp.
