!PPCStarAnyNode methodsFor:'first follow next'!

firstSets: aFirstDictionary into: aSet suchThat: aBlock
    "
        First and follow should be performed on the non-specialized tree, i.e. on a tree
        with star -> messageNode. Not on myself.
        
        The reason for that is, that:
        - I am terminal
        - I am nullable
        
        This means, I look like epsilon node for the first follow analysis. And epsilons 
        are ignored in sequences, thus sequence of StarMessagePredicate, Literal
        leads to { Literal } as firstSet and not expected { MessagePredicate, Literal }
