I was referring to the syntax for how the user actually defined an enum
not about it's implementation. Basically what I was hoping to get out of
this thread was whether it was better to allow the user to define their
own range types by specifying the base type and possibly the granularity
and default inclusiveness of the end points, or if we should just
provide the types like period and intrange?
