A property name in a nested closure interferes with a class property when refering with "this.prop"

I guess this may be a parser bug (I'm not sure).

This class is working fine:

private class TestClosure {
def test = 1
def c1 = {
def test = 2
def c2 =

{ println this.test this.test+=10 println this.test }

c2()
}
}

new TestClosure().c1()

But when we change:

def c2 =

{ println this.test this.test+=10 println this.test test = 3 }

then thing is screwed up.
'this.test' is resolved to be 'test' of the c1 closure, which is not correct.
