Chris Angelico asked: what does a negative string look like?
This is a very good question. It looks a bit like a negative number.
They really don't. Negative numbers are well defined in terms of being the additive inverse of natural numbers. String concatenation doesn't have a well-defined inverse, as you demonstrated by not actually trying to define it. It strikes me that following this line of reasoning is at best a category error. -- Rhodri James *-* Kynesim Ltd
