Sorry, I wasn't clear. I knew about this difference. What I was trying
to say was that the variables and functions that have an autoload prefix
should by default be global. Why would anyone want to create a script
local variable with autoload prefix? a script local variables can only
be accessed from with in the same script, but then if the script is
already loaded, you don't need to autoload it anymore. All the autloader
ids can and should safely be considered as global. I hope I make sense
at least for someone.
