The "fun" variant works with any table.  You just specify a list of
positions where you want hlines, e.g. '(0 1 last) or '(0 1 -1).

If you use :post you can keep your utility functions in a :noexport:
section at the bottom of your file (or even in a library-of-babel (see
org-babel-lob-ingest)) and you don't litter your code with unnecessary
stuff.  It's also usable across blocks.
