I think the issue is that matching the tail of a string is not the same as
not matching any part of it.
(find "abcde" "x") = tail "abcde"
So find can't return any part of the string in the case of a failure. Hence
the none as the response.
If you do want to position at the tail of the string when not found, you
could make a function out of this:
str: "abcde"
either temp: find head str "c" [str: temp] [str: tail str]
(You won't want the 'head if you want to search from the current position)
