Another one that I've noticed is the truism that Ada is supposed to be
good for programming in the large, or the humongous, or whatever.  I've
heard this in several different forms, along the lines of "C++ is good
for projects up to a million lines of code or so, but beyond that you
need Ada."

This theme is repeated by Ada apologists and vendors in the same voice
or with the same motivations as the "reliability" theme, and with the
same effects.  It's also repeated by those who wish to sound
even-handed, or as a concession -- a charitable way of saying "that
language must have some reason to exist -- maybe it's 'programming in
the large'...").

In any case, it makes it sound as though there is some penalty for
using Ada that dominates in small or medium-sized projects, and that
the benefits do not emerge until you reach the level of "way huge
