Some (many?) enumerations represent cycles, where incrementing from the last element takes you back to the first: the seasons, the months, the days of the week, the hues, etc. How hard would it be to write a module that lets you say something like:
enum weekdays is cycle <Sun Mon Tue Wed Thu Fri Sat> So that Sat++ eqv Sun (and a resumable control exception is thrown so that you can do something fancy whenever you return to the start of the cycle)? Likewise, how would one be able to legally say: enum seasons <spring summer autumn|fall winter> That is, to use a junction in the definition in order to provide synonyms for one of the enumerated values? -- Jonathan "Dataweaver" Lang
