lrange - Return one or more adjacent elements from a list

List  must be a valid Tcl list.  This command will return a new list consisting of elements first through
       last, inclusive.  The index values first and last are interpreted  the  same  as  index  values  for  the
       command stringindex, supporting simple index arithmetic and indices relative to the end of the list.  If
       first  is  less  than  zero,  it  is treated as if it were zero.  If last is greater than or equal to the
       number of elements in the list, then it is treated as if it were end.  If first is greater than last then
       an empty string is returned.

       Note that “lrangelistfirstfirst” does not always produce  the  same  result  as  “lindexlistfirst”
       (although  it  often  does  for simple fields that are not enclosed in braces); it does, however, produce
       exactly the same results as “list[lindexlistfirst]”

       Selecting the first two elements:

              % lrange {a b c d e} 0 1
              a b

       Selecting the last three elements:

              % lrange {a b c d e} end-2 end
              c d e

       Selecting everything except the first and last element:

              % lrange {a b c d e} 1 end-1
              b c d

       Selecting a single element with lrange is not the same as doing so with lindex:

              % set var {some {elements to} select}
              some {elements to} select
              % lindex $var 1
              elements to
              % lrange $var 1 1
              {elements to}
