> When a closure's resolveStrategy is set to DELEGATE_ONLY or DELEGATE_FIRST, resolution is different in nested closures between methods and properties of the delegate. For example, in the following, {{x}} resolves to {{f}}'s delegate (what I expect), but {{keySet()}} resolves to {{g}}'s delegate.
> {code}
> def g = {->
>     def f = {
>         {-> [x, keySet()]}()
>     }
>     f.resolveStrategy = Closure.DELEGATE_ONLY
>     f.delegate = [x: 1, f: 0]
>     f()
> }      
> g.delegate = [x: 0, g: 0]
> g()
> {code}
> Result: {code}[1, ['x', 'g']]{code}
> Whereas without the nested closure
> {code}
> def g = {->
>     def f = {
>         [x, keySet()]
>     }
>     f.resolveStrategy = Closure.DELEGATE_ONLY
>     f.delegate = [x: 1, f: 0]
>     f()
> }      
> g.delegate = [x: 0, g: 0]
> g()
> {code}
> Result: {{[1, ['x', 'f']]}}
