Curly braces

ActionScript event handlers, class definitions, and functions are grouped together into blocks with curly braces ({}), as in the following examples:

// Event handler
on(release) {
	myDate = new Date();
	currentMonth = myDate.getMonth();
}

// Class
class Circle(radius) {
}

// Function
circleArea = function(radius) {
	return radius * radius * MATH.PI
}
