Ok, added, with description in README.

NOTE: this produces a call to ActionDefineLocal (0x3c) which
is told to create a 'local' variable.

NOTE: last statement references a variable which is "local" to
      another function.

Try having ball.bounced() trace something, and see if it is printed
on bounce.
