         #list {var} {delete} <index> [amount]  Delete the item at <index>,
                                                the [amount] is optional.

         #list {var} {indexate} [key]           Index a list table for sorting
         #list {var} {insert} <index> <item>    Insert <item> at given index
         #list {var} {filter} <keep> [remove]   Filter with keep / remove regex
         #list {var} {find} <regex> <variable>  Return the found index
         #list {var} {get} <index> <variable>   Copy an item to {variable}
         #list {var} {numerate}                 Renumber a table or list

         #list {var} {refine} <keep> [remove]   Filter with keep / remove math
                                                with &0 holding the value
         #list {var} {reverse}                  Reverse the list
         #list {var} {shuffle}                  Shuffle the list
         #list {var} {set} <index> <item>       Change the item at {index}
         #list {var} {simplify} [items]         Turn list into a simple list
         #list {var} {size} <variable>          Copy list size to {variable}
         #list {var} {sort} [items]             Sort list alphabetically, if
                                                an item is given it's added.
         #list {var} {swap} <index> <index>     Swap two items
         #list {var} {tokenize} <string>        Create a character list

         The index should be between +1 and the list's size. You can also give
         a negative value, in which case -1 equals the last item in the list, -2
         the second last, etc.

         When inserting an item a positive index will prepend the item at the
         given index, while a negative index will append the item.

         The add and create options allow using multiple items, as well
         as semicolon separated items.

         The get option will return the item or the indexation. Use
         $var[<index>] to retrieve the nested data of a list table.

         The order, sort and simplify options will perform the operation on
         the given list. Optional items can be provided which are added to
         the new or existing list before the operation is executed. Sorting
         and ordering are stable.

         The indexate option prepares a table or list table for order, sort,
         filter, refine, and find operations for the given key. It is similar
         to the SELECT option in SQL.

         A size of 0 is returned for an empty or non-existent list. You can
         directly access the size of a list using &var[].

         You can directly access elements in a list variable using $var[+1],
         $var[+2], $var[-1], etc.
