you are correct. from the ''CONVENTIONS'' file:

		- A function should *not* return wrapped values like
		  {ok,Value}/{error,Reason} to indicate success or
		  failure. The assumed behaviour should be success,
		  and failures should be signalled by exceptions,
		  as described below.

    EPO guidelines 1978: "If the contribution to the known art resides
    solely in a computer program then the subject matter is not
    patentable in whatever manner it may be presented in the claims."
