ActionScript 3 :: Conflicting Scope - Global Functions And Class Methods Of Same Name

My question deals directly with ActionScript 3, although it could possibly appear in other languages. Consider the global trace function found in AS3. Calling the method requires no imports and is globally available from all classes.
class A {
public function A() {
trace("Hello, A!"); // Hello, A!
}}

Now, what if I create my own class method of the same name? In AS3, if I have a class method trace and then make a call to trace elsewhere in my class, the call is made to the class method over the global function. Essentially, I've blocked my ability to call the global trace method.
class B {
public function B() {
trace("Hello, B!"); // no output
} public function trace(s:String):void {
// do something else.
}}

Now, I know the obvious answer is to say, "don't create a class method called trace." But what if I'm unaware of the existence of the global trace function? Or what if I have a desire to "override" or "block" the global function? Is doing so bad programming? Or is this just another example of how AS3 is a poor object oriented language?
