Damian and Larry had been talking out the hell of inheritance. Lots of diagrams on the blackboard. Then Dan said: "Parrot will come with full matrix support standard, as we'll need it for the Perl 6 inheritance tree."
This rapidly descended into how to do inheritance via FFT, and what happened to the Slow Fourier Transform, and then we quickly changed the subject before Larry or Damian started taking this seriously.:-)
