Advanced scope fails on a closure return

[chiquitinxx]

This code fails translating to javascipt:

def getCallBacks(){
def callBackArray = []
def i = 0;
for(;i<3; i++){
callBackArray[i] = {return i;}
}
return callBackArray
}

def callBackArray = getCallBacks()
assert callBackArray0 == 3

Final line is:
assert callBackArray0 == 3

Problem was with empty expression in for. Never got before an emptyExpression, now just will return nothing. Javascript and groovy work same way with vars used in closures that are defined outside.
