But the java SDK API docs recommend exactly that for every class, you
override this behavior inherited from Object, wherever some other
toString() implementation makes more sense for your object, which is why
I consider this to be an implied contract.  If you don't keep the
contract, and go with the default, you deserve the results, it seems to
me.

In any case, such universal meta-programming rules would seem useful for
Ada, beyond just the idea of a style guide.  Do such exist?  Does a
repository of them exist?
