My favorite example (as Bob knows :-) although I usually like
to say "good" error messages, since that is really the
specification (being informative is one, but not the only,
ingrediant in a good error message, for example clarity and
brevity are important too, a compiler which printed the
entire RM for every message would be VERY informative :-)

Another example is to generate a GUI with good ergonomics.
