Allow optional trailing comma "," for field constraint list
-----------------------------------------------------------

                 Key: JBRULES-451
                 URL: http://jira.jboss.com/jira/browse/JBRULES-451
             Project: JBoss Rules
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Drl Parser/Builder
    Affects Versions: 3.0.4
            Reporter: Juergen none
         Assigned To: Mark Proctor
            Priority: Optional


With frequently re-arranging / adding / removing field constraints, I more than once forgot to add / remove trailing/separating commas in the field constraint list.

would it be possible to extend the drools drl syntax to allow an optional trailing comma?
e.g.
A(
  a == 1,
  b == 2, // optional trailing comma, should not yield the syntax error
)

A(
  a == 1,
  b == 2 // no (optional) trailing comma, like currently required, is also valid
)
