There's no "odd" flag, theres the overflow flag "O", and "JO" is

it's locking the front door but leaving the back door wide open.

enum foo is essentially a shortcut for enum { foo }. It’s
neither bent out of shape nor twisted. Consider that C++ added
the new keyword constexpr for the same thing.

If your implementations are based on built-in operators, you

So you have opBinary and half a dozen operators to implement. Do
you use a separate method for each operator or do you have one
method and a big static if else if to select code path?
I assume they are functionally equivalent? So its just about
style?
