RE: [boost] discrete_set class

People are thinking about your construct as a set, which is "open" in
its nature.

I suggested to borrow some terms and ideas from the area of Finite
Domain Constraint-solving. That proposal was apparently ignored, due to
the introduction of unknowns and overall whimsical appearance ;-)

I think that using terms like "domain" or "finite_domain" with the
semantics from Constraint solving would clarify that this construct,
although being extremely useful, is not a regular "set".

Ok, this is my fault.  As Joel has pointed out, I neglected to provide
documentation.  I apologize and will upload some as soon as I can.  For
now, the problem with your examples is the class expects the values of
the elements to be in the range [LO, HI].  You are trying to use values
outside the range.  My understanding of C++ is that it is undefined
behavior to convert an int to an enum when it is outside the enum's
range.
