Description

It would be great to have a possibility to omit parentheses in closure annotations like this:

@Require({it > 2})
def myMethod() {
  ...
}

and after change:

@Require {it > 2}
def myMethod() {
  ...
}

This would be nice, of course, and we already thought about it, but the problem is that we'd like Groovy to support annotations on arbitrary expressions, and that would mean that we could allow annotations on literal closures as well. So we may have a clash here as this would be ambiguous if we supported that feature.

I'm not closing the issue as "won't fix" for now, as we haven't fully studied the impact of such a change, in the light of our wish to support annotations on any expressions, including closures.
