Both you and Peter and concentrating on the faults strong typing
prevents happening and skipping over the fact that it sometimes
causes faults to be created (e.g., through the contortions that
sometimes have to be gone through to interface two libraries
making use of very strong typing in very different, and structurally
incompatible, ways).
