Typo errors : replace Has by As every where it is relevant.
Sorry, it seems when I am writing, I mostly write words as a whole inste=
ad  =

of writing letters one by one, so it happens I replace a word by another=
.

-- =

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.
