Not just more readable - consider the case where you're overriding
something:
class A
{
public function doSomething()
{
trace("Something in A");
}
}
class B extends A
{
public function doSomething()
{
super.doSomething();
trace("Something in B");
}
}
In this situation, using super.method() lets you call the parent
implementation of the method you're currently in. If you were limited to
this.method(), then you'd be trapped in an infinitely recursive loop as the
method kept calling itself...
In fact to do exactly this is normally the only time you'd use super.method().
If you're calling super.doSomethingElse() from your doSomething() function,
something is probably wrong with your OOP design...
