  what is "type checking"?

  if you could please step back to where your ignorance begins and start
  asking questions from there, rather than walk miles into the land of
  confusion before you stop to ask for directions, you would stand a chance
  of learning this stuff, rather than have your questions answered in ways
  you do not actually understand.

  let me put it this simply: in Common Lisp, objects are typed, variables
  are not.  in the C tradition, variables are typed, objects are not.  if
  this doesn't hurt when you think about it, you have not understood what
  it means for the purported object-orientedness of C++ and Java.

  suppose we blasted all politicians into space.
  would the SETI project find even one of them?
