The circle is valid, what you say is a bug in other section that crashes with valid circles,so types could prevent invalid inputs to functions. What you describe is a bug in an algorithm I don't think that is possible for a compiler to prevent bugs in algorithms, division by zero or precision errors
- xapata 9y agoType systems can do some pretty miraculous things. For example, you could distinguish between a connected and disconnected socket with types so that you don't accidentally send on a disconnected socket. I guess I'm arguing both sides now. My point is that one needs to root out the weird cases somehow and that it's often hard to have "100%" validation of inputs. One's initial understanding of what is the valid and invalid state space is often incorrect.
