==== sequence ====

  TYPES sequence(TYPE first, TYPE step, INTEGER count)

Create a sequence of numbers or vectors.


==== repeat ====

  TYPES repeat(TYPE[] item, INTEGER count)

Create a list by repeating same item or pattern.

==== resize ====

  resize(TYPES & list, INTEGER newsize, TYPE pad = nul) 

Resize list.

==== insert ====

  insert(TYPES & list, INTEGER at, TYPE[] insert = nul) 

Insert item or list of items into a list at specified position.

  insert(TYPES & list, TYPE[] insert = nul) 

Insert item or list of items at the end of the list.

==== feedin ====

  feedin(TYPES & list, INTEGER at, INTEGER count = 1, TYPE pad = nul) 

Equivalent to insert(list, at, repeat(pad, count)).

==== delete ====

  delete(TYPES & list, INTEGER at, INTEGER count = 1) 

Delete items from list.

==== remove ====

  remove(TYPES & list, INTEGER at, INTEGER count = 1)

Delete items from list. Faster than delete, does not preserve item order in the list.
  

==== include ====

  include (TYPES & list, TYPE[] itms) 

Append items to end of list, but only items not already in the list.
  

==== exclude ====

  exclude (TYPES & list, TYPE[] itms) 

Delete items from the list. All occurences of each item are removed. Does not preserve item order in the list.
  
  excludef(TYPES & list, TYPE[] itms)

Delete items from the list. Only the first occurence of each item is removed. Does not preserve item order in the list.

==== pack ====

  pack(TYPES & list, TYPE[] src, INTEGER at = 1, INTEGER step = 1)

Pack items from source list: list[n] = src[at + (n - 1) * step]

==== unpack ====

  unpack(TYPES & list, TYPES src, INTEGER at = 1, INTEGER step = 1))

Unpack items from source list: list[at + (n - 1) * step] = src[n]
