In JBoss Rules 4 the multiple assignment of a variable to an object definition 
gives an error, while it worked in 3.X. Not sure what's conceptually correct: 
(Have not noticed any impact yet):

rule "Collect Test" salience 70
     when
         $person      : Person( name == "Bob", $likes : likes )
         $person      : Person( age== 42 )

'$person' repeated twice!
