That's correct. I like the GNAT method principally how it works with units.=
 What I absolutely dislike is that (since Ada is case insensitive) they inv=
ent new unit and prefix symbols. Their dimensioned text output (they call i=
t IO, which is a lie) is catastrophic. see

its_with_GNAT_GPL_2013-AUJ35.1.pdf

All this is corrected in my design. If these ideas could influence the GNAT=
 method, this would be ideal. But there does not seem to be much interest i=
n the method by their clients since nothing has changed since 2013.
