I used this in a small unit library (partially accessible on github), to obtain code like: auto distance = 100.km; auto speed = 130.km/h; // division works, too. auto timeToDestination = (distance/speed).hour; // distance/speed gives seconds => transformed in hours. It was a nice exercise in using UFCS and mixins to create your own unit library (not only IS, but ay kind of unit library). And, you know what? I *never* used it after coding it. These examples are cute, they make for nice blog posts for F#, but the real-world usage is dubious to me (I know they were space-programs crashes) I quite like the implicit message in units: use the type system to help you catch errors are compile-time. Add to that a nice syntax and a showcase for D's generational capabilities and it's quite nice. But, to my eyes, it's but a toy.
