Use javascript for a while.  First time you get 23 as the result of
adding 2 and 3 and things and you'll end up writing "unify" on a piece
of paper and then spend 4 hours burning it.

Here's another puzzle:

  foo = new Array();

We now have `foo' bound to an array of three integers.  If you do this,

  for (var i in foo) alert("i = " + i);

you'll find that `var i in foo' iterates `i' over the indexes.  Odd
but acceptable, right?

Now try this:

  for (var i in foo) alert("i = " + (i+0));

(So where was that piece of paper...)

          ((lambda (x) (x x)) (lambda (x) (x x)))          Eli Barzilay:
