DESCRIPTION
       The list argument must be a valid Tcl list.  This command returns the string formed by joining all of
       the elements of list together with joinString separating each adjacent pair of elements.   The  join-String joinString
       String argument defaults to a space character.

EXAMPLES
       Making a comma-separated list:
              set data {1 2 3 4 5}
              join $data ", "
                   -> 1, 2, 3, 4, 5

       Using join to flatten a list by a single level:
              set data {1 {2 3} 4 {5 {6 7} 8}}
              join $data
                   -> 1 2 3 4 5 {6 7} 8
