<<Eiffel has had that for years, so your productivity boost is only over the
C languages. For the other several hundred percent you need to apply DBC,
even if only methodologically.>>


Any time that people claim giant factors in productivity improvements, they
do the technology for which they make the claim a disservice.

The trouble is that when anyone reads a silly claim like the above, they
tend to assosicate it with everyone who has been supporting the feature.
Certainly Betrand Meyer is not going to claim a "several hundred percent
improvement" in  productivity from using DBC. Just that it can provide
in some circumstances a significant productivity boost.

Ada has been hurt in the past by ludicrous claims, and it is a common
phenomenon.

Of course when a methodology, or language, or technique, or whatever,
has the effect of resulting in working code instead of catastrophic
non-working code, then in some sense the improvement in productivity
is infinite, but this is not a useful quantitative way to look at things.
