Prefix 'and' and infix 'and' not interchangeable
------------------------------------------------

                 Key: JBRULES-1422
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1422
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Drl Parser/Builder
    Affects Versions: 4.0.2
            Reporter: Alexandre Gattiker

The documentation on the 'and' Conditional Element seems to imply that these constructs are equivalent:

		$p1:Entity($code1:code)
		not (and
			$p2:Entity(code == $code1)
			 eval(MyStaticClass.match($p1, $p2))
		)

		$p1:Entity($code1:code)
		not (
			$p2:Entity(code == $code1)
			and eval(MyStaticClass.match($p1, $p2))
		)

Actually, the first version crashes with this message:

unknown:93:7 Unexpected token 'and'[96,2]: unknown:96:2 mismatched token: [@792,3685:3685=')',<12>,96:2]; expecting type THEN

I'm on drools 4.0.2 and mvel14-1.2.8.
