"Inevitably, the programmed validity checks of the defensive
programming approach will result in run-time overheads and, where
performance demands are critical, many checks are often removed from
the operational software; their use is restricted to the testing
phase where they can identify the misuse of components by faulty
designs. In the context of producing complex systems which can
never be fully tested, this tendency to remove the protection
afforded by programmed validity checks is most regrettable and is
not recommended here." ---M. R. Moulding, "Designing for high
integrity: The software fault tolerance approach," Section 3.4. In
C. T. Sennett, ed., High-Integrity Software, Plenum Press, New York
and London, 1989.
