NAME
       llength - Count the number of elements in a list

SYNOPSIS
       llength list
_________________________________________________________________


DESCRIPTION
       Treats list as a list and returns a decimal string giving the number of elements in it.


EXAMPLES
       The result is the number of elements:
              % llength {a b c d e}
              5
              % llength {a b c}
              3
              % llength {}
              0

       Elements  are  not  guaranteed  to be exactly words in a dictionary sense of course, espe-
       cially when quoting is used:
              % llength {a b {c d} e}
              4
              % llength {a b { } c d e}
              6

       An empty list is not necessarily an empty string:
              % set var { }; puts "[string length $var],[llength $var]"
              1,0
