I didn't want to mention it, but seeing as you brough it up, I imagine this
quote from your original message is also a typo:

>A more realistic estimate, using 10 kSLOC/day and 5 errors/kSLOC, is $1.8M over
>6 years to increase the number of errors by at least a factor of 10.

I can't say I know of anyone who has ever written 10kSLOC/day :-)

Apart from that, it was certainly a well presented argument in favour of
retaining Ada.
