Is there a reason you find yourself working with strings as opposed to
buffers?  I've seen people try to force functional paradigms on Emacs
when they do stuff like creating a list of lines in a buffer then
iterating over these instead of using the (faster) buffer searching
mechanisms.  My worry is that functions like these, while useful per se,
might make more people inclined to write unideomatic and wasteful code.
