breaking nested loop in haxe - which solution is the best ?

final solution; thanks Joshua !

canPlace = 1;
for (y in 0...height)
{
    for (x in 0...width)
    {
	    if (mapArr[x][y] != ' ')
	    {
			canPlace = 2;
			break;
	    }
    }
    if (canPlace == 2) break;
}

nested loop break - original code

canPlace = 1;
for (y in 0...height)
{
    for (x in 0...width)
    {
	    if (mapArr[x][y] != ' ')
	    {
			canPlace = 2;
			// we want to break here ! but we can't because of the nested loop ! and there is no goto in haxe :(
	    }
    }
}

solution 1

canPlace = 1;
(function() { // self invoking local function
	for (y in 0...height)
	{
		for (x in 0...width)
		{
			if (mapArr[x][y] != ' ')
			{
				canPlace = 2;
				return;
			}
		}
	}
})();

solution 2

canPlace = 1;
for (y in 0...height)
{
    for (x in 0...width)
    {
	    if (mapArr[x][y] != ' ')
	    {
			canPlace = 2;
			y = height; // cause the outer loop to break
			break; // break the inner loop
	    }
    }
}

solution 3

canPlace = 1;
var exitedInner:Bool = false;
for (y in 0...height)
{
    for (x in 0...width)
    {
	    if (mapArr[x][y] != ' ')
	    {
			canPlace = 2;
			exitedInner = true;
			break;
	    }
    }
	if (exitedInner) break;
}

solution 4

var canPlace = 1;
var y = [for (i in 0...height) i];
Lambda.foreach(a, function(y) {
	for (x in 0...width)
	{
		if (mapArr[x][y] != ' ')
		{
			canPlace = 2;
			return false;
		}
	}
	return true;
});
