> 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.
