Oh, I disagree with this point of view. Circle is certainly a value, i.e. a full-fledged function, as Brian Beckman correctly surmised.
Interesting. I don't claim that my viewpoint is the One True Path, but I don't think it's wrong, either. I know you're interested in the teaching of Haskell, and the fact remains that I *was* confused by data constructors when I learned Haskell, and it *did* help me to stop thinking of them as functions.
When I saw 'data' the first time, it looked for me similar to C's unions, i.e. a data structure. Sometime later I got the point that constructors are also functions. :-)
