As this is about genericity, I would like to understand: what kind of  =

curve is one =E2=80=9CGeometrically exploding=E2=80=9D ? I could not fin=

explanation on the web and don't have anything in my background about it=

I remember in the past (past year I think), we talked around generics  =

hierarchy and generic packages as formal parameters. You had warned abou=
t  =

possible complexity explosion in this area: is this about the same ?

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
