AS 1 and 2 actually do have a strange (buggy?) way to handle function
definitions in block statements like for, catch, try, finally and if. As
there is no block-level scope in ActionScript we'd expect that function
definitions are scoped to the parent timeline / surrounding scope - however
they are not:
{
function test(){}
trace(test);
}
Output in AS 1 & 2 : undefined
In AS3 however function definitions inside these block statements do behave
as expected and are scoped to the surrounding scope (local scope of the
function that holds the block or to the timeline the code is on).
The output of above sample in AS3 is therefore: function Function() {}

Subject: [Flashcoders] strange scope behaviour
Hello,
just take a while and try this:
function area55() {
if (_root) {
trace("_root true")
function f() {
var g;
var h;
}
}
//g=0
trace("f "+f)
function h() {
}
function jj() {
for (var i in this) {
trace(i+" : "+this[i]);
}
}
jj();
}
area55();
and this:
function area55() {
function f() {
var g;
var h;
}
//g=0
trace("f "+f)
function h() {
}
function jj() {
for (var i in this) {
trace(i+" : "+this[i]);
}
}
jj();
}
area55();
why the function f is not even seen, after for sure the if statement is
true....
