[rules-users] compiled package too big

[Wolfgang Laun]

One proposal: Don't put the values to which you compare the attributes into
rules; put them into additional facts. Consider:

rule "bounds_a_1_10"
when
   Fact( a >= 1 && <= 10 )
then ... end

and  similar for 11:100, 101:1000,... could be handled by a single rule and
a set of Limit-type facts:

rule "bounds_a"
when
  Limit( ?low : low, ?high : high, ?x : x )
  Fact( a >= ?low && <= ?high )
then
   // enact consequence, parameterized with ?x
end
