NAME
  lreplace - Replace elements in a list with new elements

SYNOPSIS
  lreplace list first last ?element element ...?

DESCRIPTION
  Lreplace returns a new list formed by replacing one or more elements of
  list with the element arguments. First gives the index in list of the
  first element to be replaced (0 refers to the first element). If first
  is less than zero then it refers to the first element of list; the
  element indicated by first must exist in the list. Last gives the index
  in list of the last element to be replaced. If last is less than first
  then no elements are deleted; the new elements are simply inserted
  before first. First or last may be end (or any abbreviation of it) to
  refer to the last element of the list. The element arguments specify
  zero or more new arguments to be added to the list in place of those
  that were deleted. Each element argument will become a separate element
  of the list. If no element arguments are specified, then the elements
  between first and last are simply deleted.

EXAMPLE
  % lreplace {ABC DEF {GHI JKL} MNO} 3 3
  ABC DEF {GHI JKL}

  % lreplace {ABC DEF {GHI JKL} MNO} 3 3 {PQR STU} VWX YZ
  ABC DEF {GHI JKL} {PQR STU} VWX YZ
