> In a script, this works:
> c = { println 'works' }
> c()
> whereas this one doesn't:
> def bind = new Binding(c: { println 'does not work' })
> def t = { c() }
> t.delegate = bind
> t()
> They both define a 'c' property in the binding which happens to be a closure. In the first case, the closure get's called as Groovy apparently tries to get the binding property and invoke it if it's a closure; in the latter, the delegate of the closure is a binding with a property 'c' that is a closure, but c() still doesn't work.
> I debugged this and there is actually an if in MetaClassImpl that checks if the 'this' object is a Script, and if so, a property with the name is retrieved and a call() method is called. (MetaClassImpl#invokePropertyOrMissing:1089 in Groovy 1.8.6-all from maven central).
