Only 2-5% of your bugs are purely logical!? While I'd agree that once your
compiler produces executable code the bugs left are of the logical
variety, that number seems incredibly low (or the number of bugs you
initially have is ridiculously high ;-) ). Back to the topic: how much of
this would you attribute to Ada's use of types versus its very thorough
compiler (that checks a wide range of problems, not all of which may be

Excellent! You seem to have what I was looking for from the initial
poster: a specific example. Can you post one please? I'd really like to
better understand your perspective. Thanks!
