       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 and last are index values spec‐ │
       ifying  the first and last elements of the range to replace.  The index │
       values first and last are interpreted the same as index values for  the │
       command	string	index,	supporting simple index arithmetic and indices │
       relative to the end of the list.	 0 refers to the first element of  the │
       list,  and  end	refers	to  the	 last element of the list.  If list is │
       empty, then first and last are ignored.

       If first is less than zero, it is considered to	refer  to  before  the
       first  element of the list.  For non-empty lists, the element indicated
       by first must exist or first must indicate  before  the	start  of  the

       If  last	 is  less  than	 first,	 then  any  specified elements will be
       inserted into the list at the point specified by first with no elements
       being deleted.

       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.	  If list is empty, any element arguments are added to the end
       of the list.

       Replacing an element of a list with another:
	      % lreplace {a b c d e} 1 1 foo
	      a foo c d e

       Replacing two elements of a list with three:
	      % lreplace {a b c d e} 1 2 three more elements
	      a three more elements d e

       Deleting the last element from a list in a variable:
	      % set var {a b c d e}
	      a b c d e
	      % set var [lreplace $var end end]
	      a b c d

       A procedure to delete a given element from a list:
	      proc lremove {listVariable value} {
		  upvar 1 $listVariable var
		  set idx [lsearch -exact $var $value]
		  set var [lreplace $var $idx $idx]
