OK, it refers to 2.8. Still feel the wording could be more readable here=

It's not about type, its about signature: imported subprogram has a  =

convention too, and it should have the same legality requirement as acce=
ss  =

to subprogram has on the signature.

Later after a silly error in a text, I get a compiler warning about an  =

did not get a warning, but an error instead. It seems access to subprogr=
am  =

with a Convention have this requirement, I would expect the same for a  =

imported subprogram with the same Convention too.

That's why I had a feeling something is missing.
