 Haxe expands upon the `get`/`set` functionality of ActionScript to provide nuanced property access support. For example, a read-only variable can be declared without a getter and an extra variable.
 
-When defining a getter or a setter function, Haxe requires the "get\_" or "set\_" prefix. This helps reflection work more easily, and ensures consisten behavior, even on environments that do not support getters and setters natively.

+Note in these examples how in Haxe you can generate a default getter or setter by using the `default` keyword in a property declaration.

+ActionScript has multiple kinds of loops. There are `for ... in` loops, `for ... each` loops and `for` loops. Haxe simplifies this syntax to a single `for ... in` loop. To iterate over keys instead of values, use `Reflect.fields` for anonymous objects, or `.keys()` for maps. Both ActionScript and Haxe support `while` loops. If your loop is not a simple iteration, you must use a `while` loop in Haxe. ActionScript loop variables are visible outside the loop, while Haxe loop variables are not.
