That's great, thank you Simon.

I did encounter one strange compiler error.
A bit of trivial code that has been passingall
regression tests for a decade suddenly failed thus:

> raised CONSTRAINT_ERROR : erroneous memory access.

(without a line number).

Binary search in my code narrowed it down to this:

> full_ruler : constant String (1 .. 80) := (others =>  '_');

> log_line(full_ruler, iff); -- <====== FAILS HERE!
> end log_rule;

If I replace:

log_line(full_ruler, iff);

by:

log_line(String'(1..80 =>  '_'), iff);

the exception goes away!
