Changes between Version 21 and Version 22 of immutablelist

v21	v22
10	10	* {{{ImmutableList}}} is immutable, so it can not be modified

12		As a simple comparison, suppose you need a list of all integers between 100000 and 200000. You could write a loop to fill ~~1000~~ elements of an {{{ArrayList}}}. This takes you about a megabyte of memory plus the time of filling the array. Alternatively, you can use {{{RangeInt(100000,200000, 1)}}}. This takes almost no memory (storing 3 BigDecimals plus some overhead), and no additional time.

14	14	This mechanism is especially useful when the list elements have to be generated on an as-needed basis. For example when large lists are used, when the list elements are expensive to create, or when you already know that the user of the list will only pick a few items from the list, or even just wants to know the size of the list.
