But this example is easily written using the current idioms,
the issue being one of ease of inheritance, but it is not
clear that this is a compelling argument.

Currently we don't see any demand for doing anything in this
area, so there are no plans. It's a lot of work, and it is not
something that will get done without a very clear demand. I
certainly agree it would be nice to use GNAT as an experimental
vehicle for looking at some of these issues.

Perhaps the most practical thing is to devise some kind of
source-to-source translation kludge as a first experiment,
since that can be done without digging into what are some of
the most delicate parts of the front end (you would have to
know a LOT about GNAT internals to implement Tuck's proposal
:-)
