This solution would call for precise documentation (advantages,
disadvantages) etc. pp. Plus a quick summary ("functions are faster") for
the beginner.
Otherwise the same problems as with "access all" will arise. Many programers
use "access all" all the time - even when not needed, ignoring the
diadvantages.

See above. Have you heard of GNATs "pragma Pure_Function"?
Prehaps making function even more restive plus procedures with return plus a
"functions are faster" statement might do the trick.
