"In ActionScript 3.0, primitive values and their wrapper objects are,
for practical purposes, indistinguishable. All values, even primitive
values, are objects. Flash Player treats these primitive types as
special cases that behave like objects but that don't require the normal
overhead associated with creating objects."

"Unlike in ECMAScript 3, there is no distinction between objects and
primitive values. All values can have methods."

In AS2, your example would of course work but only because the Flash Player
would create a temporary String object with your string literal, then get the
object's length property and return the value, and then delete the temporary
String object it created. So yes, all method calls and get/set on property
values would work just fine on literals in AS2, but only because Flash Player
used to create temporary objects and delete them as soon as the operation ended.
Thus, when you needed to call multiple methods on a string for exemple, it was
more efficient to explicitely create a new instance of the String object and
call those methods on the object rather that just calling those methods on a
string literal.
But it seems that this is no longer true in AS3, that String objects and string
literals are now treated the same by Flash Player 9 using AS3 (there are no
more implicit temporary String objects created by the Flash Player).
