Don't despair. The dot '.' as a Lua pattern has a special meaning - "any
character". If you do not need to use special patterns as separators,
you can use the fourth (optional) parameter of string.find - 'plain'.
Quoting the manual:
A value of true as a fourth, optional argument plain turns off the
pattern matching facilities, so the function does a plain "find
substring" operation, with no characters in pattern being considered
When you change both calls to string.find(self, delimiter, from, true)
then the code behaves as you would like.
