[rules-users] Bug in 5.1 : function w/o parameter type is a no-no

The RTE is caused by following DRL.g in writing a function; it says you can omit the type for a parameter. A function like this causes the crash: function inf sqr( a ){ return a*a; } Untyped parameters may be used in queries. I suppose it will be necessary to use different NTs for parameters and param_definition.
