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,
orif we should just 
 
provide the types like period and intrange?
