[rules-users] New DSL question...Interpreting constants...

Given the following rules (contrived example): rule "Monetary 1" when Currency(typeID in (CurrencyConst.DOLLAR, CurrencyConst.EURO, CurrencyConst.YEN)) then insert(new Fact()); end rule "Monetary 2" when Currency(typeID in (CurrencyConst.RUBLES, CurrencyConst.WON)) then insert(new Fact()); end Is it possible to map constant values into a DSL? So the above rules could be partially rewritten as: rule "Monetary 1" when Currency is one of DOLLAR, EURO, YEN then insert(new Fact()); end rule "Monetary 2" when Currency is one of RUBLES, WON then insert(new Fact()); end
