". simplest case"
' ' join: #('hello' 'world').                                      "=> 'hello world' "

". showing toString auto-conversion " 
' ' join: #('hello, this is value: ' 123). "=> 'hello, this is value: 123' "

". joiner is not only a space, the case of CSV file production "
', ' join: #('name'  'last name' 'email').                         "=> 'name, last name, email' "
