sub function scoping is a bit flakey... (eg. it's predicable as long as you know the rules..

var a = 1;
function b() {
	println(a);
}

Will work, because a is in the global scope.


function b() {
	var a = 1;
	function c() {
		println(a);		
	}
	c();
}

Will work as the compile knows that c is a local function, and gives c all the variables in b to the call.


function b() {
	var a = 1;
	var c = function () {
		println(a);
	}
	c();
}

Will not work - as at present, the compiler does not know that c is a local function
It could be fixed by testing c on the call - to see if it was defined within this scope or above.. 
- if it is this scope then call context could be kludged...
