List variables losing their indexes when used in functions, why?

[pepper82]

Why do list variables lose their indexes when used in functions? Is it a known bug, is there any workaround?

function sortList(list: objects):
    set {_sortedList::*} to {_list::*}
    loop {_list::*}:
        add 1 to {_count}
        set {_indexes::%loop-value%} to loop-index
        if mod({_count}, 20) = 0:
            wait 1 tick
    loop {_sortedList::*}:
        set {_current} to {_indexes::%loop-value%}
        broadcast "%{_current}% - %loop-value%"

command /lis:
   trigger:     
      set {_test::bronko} to 100
       set {_test::alvin} to 5000
       set {_test::marviina} to 22
       sortList({_test::*})

This is intended behavior, sorta. Skript is strictly pass-by-value, not pass-by-reference (like java), so every time you pass around a list to a function, Skript creates a brand new list and copies over the values. This is why Skript discards indexes; it simply reconstructs the list in order.

Workaround: use global lists. Pass the variable's name as text and simply access the list like any other global variable.

function accessList(var: text):
    loop {%{_var}%::*}:
        broadcast "%loop-index%"
