 * work_issues:   => see comment 10


Comment:

 * Added two minor commits, please cross-review
 * The description of `iter_process` does not explain why a user would want
 to have a simple iterator. Could you elaborate and/or provide an
 illustrating example (for simplicity, for finite input instead of an
 infinite word) on how the standard and the simple iterator differ?
 * IMHO, there should be doctests for all error conditions in
 `_iter_process_simple_`
 * I do not understand the code of `_iter_process_simple_`:
   - why do you need to set `output = outputs[0]` and iterate over `output`
 instead of `outputs[0]`?
   - why do you reset `outputs[0] = []` at the end?

   Could you please add comments on that?
 * Please add a `SEE ALSO` block for `_iter_process_simple_` even if it
 does not currently show up in the reference manual.
