Improve Function feature
------------------------

                 Key: JBRULES-1430
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1430
             Project: JBoss Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: All
    Affects Versions: 4.0.4
         Environment: all
            Reporter: longDuck dong
            Priority: Minor


The current design of the Function is a bit limiting. for example, if I want to write a function to insert, update or retract facts, the current design does not support it. According to the docs http://downloads.jboss.com/drools/docs/4.0.4.17825.GA/html/ch06s04.html, functions are just helper methods. It would be more powerful if the function always passes the workingmemory to the function. This way, the functions can easily access the globals or access the rule engine. Basically, something similar to JESS funcall http://herzberg.ca.sandia.gov/docs/70/api/jess/Funcall.html.

It also makes it easier for developers to encapsulate common actions in the consequence in a function and use it easily from a DSL. The pattern is well proven in CLIPS, JESS and haley.
