>
> Allow for use of implicit declared/bound variables inside predicates and return value expressions. Ex:
> package org.drools;
> global java.util.List results;
> global java.lang.Double factor;
> rule "test implicit declarations"
> 	when
>  	    // implicit binding
> 		Cheese( type == "stilton", ( price < 20*factor ) ) 
> 		// late declaration
> 		Cheese( price < ( price * factor ), ( price < price * factor ), price : price  ) 
> 	then
> 		results.add( "Rule Fired" );
> end
> The "price" variable is implicit declared and bound to the "price" field to be used inside the predicates and return values. It also allows for late bindings.
