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, especially 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
