I feel the last sentence (previous text was quoted for context), may be =
a  =

good reason to mitigate some (bad) evaluation of UML or UML- like  =

representations. It seems their experience shows some graphical  =

representation at some level may help. This does not really advocate for=
  =

UML, rather for some kind of multi-dimensional representations, like  =

graphical representations are.

-- =

There is even better than a pragma Assert: a SPARK --# check.
--# check C and WhoKnowWhat and YouKnowWho;
--# assert Ada;
--  i.e. forget about previous premises which leads to conclusion
--  and start with new conclusion as premise.
