And it is also available to USERS of the class as well. So rather than needing to remember a particular value to be passed into a method or return values, the class itself can define named constants.
But this is beside the point, because ::CONSTANT already exists and has proven to be useful. The only change here is an expansion on how the constants can be defined. The TwoThirdsPi case is an excellent example. To do that with the current directive, one would have to manually make the calculation using the value for pi, then type that number on to a separate ::CONSTANT directive. I've encountered a number of situations where I've had to do a manual calculation to define constants where being able to use an expression would have made the definition a lot simplier.
