Hi Graeme,
Speaking of annotations, in Java 8, there's "repeated annotations" which
hasn't yet been implemented.
Now onto your question...

Indeed that would be nicer, but... (although it's not supported today),
we'd like to be able to also annotate closures.
@IgnoreIf( {...} ) is indeed an annotation with a closure parameter, but
@Foo {...} could be an annotated closure.
What's interesting with allowing annotations pretty much anywhere is that
AST xforms could also be applied anywhere annotations are allowed.
So this would open some interesting perspectives for AST transformations.
