Sure there is way to... (it must be)

Sorry for being a bit out of topic, I would like to ask you a question, =
as  =

it seems you know about the sate of the art. Please, do you know if ther=
e  =

are accessible documents about balancing intuitionistic logic vs classic=
al  =

logic in this area ?

-- =

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.
