hehe... no, no. The quote said "flaws". Not a specific one. Flaws are
errors as we know them. You can test for the presence of the ones we
know, the specific ones. And you can test for the absence of these
specific ones. But you can't test for the absence of any flaw. That
would be akin to testing the presence of anti-flaws. What is a
non-error? A non-flaw? It's a non-existing flaw, it doesn't exist. If
could define and measure that to the extent that you can test for it,
then Dijkstra can be proved wrong :)

Until then the invert of presence of flaws is absence of flaws. And we
can only test for the former.

Cheers,
Frank
