To expand on this slightly:
Setting aside the implementation details, which are not of concern,
-error- is best thought of as a wrapper for -display as err- with some
generic message followed by -exit- and a non-zero return code.
Thus, if you want a different error message, or (less commonly) you want
a different or specific return code, you should fall back on -display-
followed by -exit-. It's certainly good style to add the return code.
