Description

def re {
if (i ==1) return i
1.times

{ re(--i) }

}

print re(4)

The re(--i) was not recognized inside the closure.

If this is supposed to be such, it's a real limitation.

Suppose I want to visit a tree...

def visit(node) {
if (node is a leaf)

{ //.. }

else {
node.children.each

{ visit(it) }

}
}
