Along similar lines, is there any good reason that the predicate error/1
is defined in the module "require"?
For a while I kept forgetting that I had to import "require" for the
following to work..

	% Res is an io__result(T)
	(
	    Res = error(Error),
	    io__error_message(Error, Msg),
	    error(Msg)
	;
	...
	)
