A variable declaration is processed before statements. Therefore, it
does not matter if it is inside or outside a loop.
myClass = new MyClass();
trace(myClass); // Output: [object MyClass]
while (false) {
var myClass:MyClass;
}

AFAIK, using implicit casting rather than explicit in this case is faster, so
A1 in your examples is faster than A2. Also, it's better to move your variable
declaration outside the loop:
var i:int = myArray.length;
// Variable is declared once here and then reused
var myClass:MyClass;
while (i--)
{
myClass = myArray[i];
}
Good luck,
