I'm not sure what you want to show with this, but if you want to minimize
code there are other solutions:

def new_thing
  thing = ( something() ? TkcLine : TkcPolygon ).new
  thing.configure('smooth', '1')
  thing
end

Note that your method relies on the implementation of #configure to yield
the proper return value.  IMHO that's bad practice since this requires more
of #configure than necessary.
