Say, we're looking for 'e' in a string, but only for those on every 2nd place.

declare_find ('e', "Maybe I should try to explain in Dutch")
integer i
i = find_next ()
while i / 2 != floor (i/2) or i = 0 do
    i = find_next ()
end while
if i then
    puts (1, "Found a \'E\'  at some 2nd place ")
else
    puts (1, "Not found!")
end if

This is without the syntax. The new 'interface' of find allows us to do this,
but now, it doesnt allow us to use it in the
normal way, or to use it in the way you suggested (returning *all* results).

This means, we would need to rewrite the *same* algorithm three times, for three
different uses.
