[rules-users] accumulate min over java.util.Date

Now don't be hasty with a JIRA. Using Comparable for the arguments of the
min and max accumulate functions will give you a result that is --
Comparable. So:

  $min: Comparable() from accumulate( Schedule( $d: date ), min( $d ) )

OK, this will give you the minimum data, bound to $min, although it won't
let you write any constraint for the "Comparable" result fact. But, what's
worse, it will not let you write

  $min: Number( intValue > 100 ) from accumulate( X( $y: y ), min( $y ) )

any more (unless I'm very much mistaken).
