@oxnrtr It's terrible! Why would you choose the hassle of types when you can just cover everything with simple tests? ;) - Show replies

@psnively@propensive@oxnrtr I gave an example at ScalaDays: I create a Pos type that promises to never hold a non-positive integer. -
@psnively@propensive@oxnrtr The type checker will ensure only a Pos is passed to methods that take Pos, not that the integer is positive.
