I was thinking more like saying kilo=1000 and automatically getting kilograms, kilometers, kilomiles, etc. Also foot=0.3*meter or some such, and then automatically getting foot/second from meter/second. > > Dealing with things like "area=length*length*length" as another > > example. > > Yes, we'd want to define secondary types in terms of primary types. area=length*length is easy. volume=length*length*length is harder, because you would need to automatically generate the intermediate type involved in the volume. I.e., if "area" weren't defined, how would you define operator "*"(l,r : length)? -- Darren New San Diego, CA, USA (PST).
