If i have a function and im strict typing: such as

private var x:Number

public function foo(y:Number){  
x = y;  
}

public function foo2(y:MovieClip){  
x = y;  
}

obviously the second doesnt work because y is a movieclip and x is a number, but i want to be able to set x to whatever type is being passed in.

is this possible??
