In @CS it fails to compile in all 3 cases.
I'd actually expect the static case ({{Container.staticC()}}) to fail as well.
There is a reason why Closure properties are callable, AFAIU in the early times
it was common to define a property with Closure type instead of a method. If
the instance case ({{container.instanceC()}}) will work, then what should
happen here?
{code:groovy}
class Callable {
def call() {
42
}
}
class C {
def call = new Callable()
}
class Container {
def c = new C()
}
def container = new Container()
container.c() // ?
// try container.c()
// then try container.c.call() as if it was written explicitly
// which in turn should try container.c.call.call()
// which in turn should try container.c.call.call.call()
// ...
{code}
