Thanks for the review and the catch. My bad, I incorporated some grammar changes to get us closer to using javacc 6.0; this resurrected another case of 'block vs set' ambiguity. I agree that whether or not an annotation is present should not change the nature of what is evaluated; but annotating a block containing one expression should be favored over annotating a set literal. I'll restore the previous behavior and will try finding a 'better' rule. Cheers Henrib
