It might be too late when designs involving anonymous access
types become issues, but then any design can possibly
have fewer issues if the Ada Rationale is first consulted.
I'm concluding this in part observing designs of programmers who
have chosen to transport a pointer-based mind set to Ada.
This means, they are perhaps not aware of the Rationale.

As an additional consequence, if GNAT advises to use pointer
types, programmers may not always be given the best advice
from a design point of view, only from a compiler that cannot
undo designs.
