lreplace - Replace elements in a list with new elements
lreplace list first last ?element element ...?
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.
