Where's that definition from? For me .succ was just the backend for prefix and postfix ++, which desugar to $thing += 1 (except for strings, where it's magic). > Neither does it make sense for > real numbers.

Well, Real implies ordering (at least to me ;-), I don't think we have a class or role for countability. >> You do have a pugs commit bit, don't you? >> If you find errors, feel free to correct them in the synopsis. > I do.

The code and tests are later adapted at whim, or so ;-) Cheers, Moritz
