They seems to have an affinity for very short names. This would need  =

evaluation (may be good at some point, less at some others)

For that one, the merit does not come to _T, but rather to _Any_Suffix. =

We've talked about it already, this was about the _Type suffix. This _T =

works the same way.


-- =

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.
