After reading the source, I think the correct implementation would be to
allow you to specify an overriding succ function on the objectrange
constructor that is used instead of
_each: function(iterator) {
var value = this.start;
while (this.include(value)) {
iterator(value);
*value = value.succ();
*}
Becomes ->
_each: function(iterator) {
var value = this.start;
while (this.include(value)) {
iterator(value);
*if (this.alternateSucc) value = this.alternateSucc(value); else value =
value.succ();
*}
Then the date prototype could have various succ's added to it-
As for setting alternateSucc on the range object, i'll leave that to the
experts.
