RULES

Here you can configure advanced rules based on RPN expressions. Check out the wiki page about the RPN Rules module to know how to use them.

Configuration
When set, variables will not be forcibly reset to null after the last rule finishes execution and garbage collected by the RPNlib. Once defined, they will be available each consecutive rules loop unless they are manually removed through unref. Mind that referencing a non-existing variable through $ will immediately stop the rule execution, to either use the variable value or a null it should be prefixed with a & instead.
