Thanks Brian,

I added

   def sendStr
     methods = { 'str0' => [ 'using "tell_it"', "tell_it" ] ,
               }
     methods.each { |keyval|
       send keyval[ 1 ][ 1 ].intern, keyval[ 1 ][ 0 ]
       send keyval[ 1 ][ 1 ].to_sym, keyval[ 1 ][ 0 ]
     }
   end

and learned: When in doubt, use ri (String#to_sym wasn't mentioned
in "ProgrammingRuby.chm").
