Actually my problem was that I couldn't find what I was supposed to put
instead of "-- What here?" to make my example work. It didn't
occur to me that nothing was the correct answer, and all my attempts at
declaring subprograms from the interface I.T where rejected by GNAT
(and it still feels a bit weird to publicly declare having an interface
without explicitly declaring any of the associated subprograms).

Actually it almost occurred to me, but my attempt with nothing was
reject by GNAT because I had something like
"type T is new A.T with limited record ..."
which produces a non-obvious error message. I should have investigated
further on the minimal example instead of the real code.

Anyway, problem solved, sorry for the noise /o\
