On page 165 sec 5.5.2 says
Therefore, the Groovy team has decided that inside a closure this doesn't refer to the closure object but to its owner: the object in whose scope the closure was declared.

then: how can I refer to the closure object, within the closure object ?

Re: this inside closure
Hi Jorge,

there are a few use cases when you ever want to do that, e.g. when a closure wants to call itself for recursive algorithm. In this case you need a reference to the closure from the enclosing scope like so:

def cl
cl = { println cl }

// calling it
cl()

cheers
