How to enable AHK_L features in AutoHotKey?

问题

I am running AHK_L which I downloaded here:

http://l.autohotkey.net/AutoHotkey_L_Install.exe

By all accounts, running the following script should break standard AHK, but popup three Msgboxes in AHK_L.

arr := Array("b", "a", "c")
Loop, % arr.len()
   Msgbox, % arr[A_Index]

I get nothing; no error, and no Msgboxes. Why is this happening to me? AHK_L version 1.1.09.04.

More specifically, why does this forum post:

http://www.autohotkey.com/board/topic/45876-ahk-l-arrays/

... contain mostly commands that don't work? Are these from an older version of AHK_L? Etc.

Here you go..

arr := Array("b", "a", "c")
Loop, % arr.MaxIndex()
{
    Msgbox, % arr[A_Index]
}
