This loop is fragile: if FUNCTION moves point backward in the buffer,
it may loop infinitely, or if it moves forward, it may skip some
paragraphs. I’d maybe wrap the funcall in a save-excursion.
More to the point[sic], you calculate and cache the END position as an
integer. So if your FUNCTION reduces the length of the buffer text,
you may never reach END. Should probably place a marker there, or
check for (region-end) or (point-max) every time.
