Re: [rules-users] counting facts of a kind

Good to know. OTOH, is there any good reason for count() having an argument at all? Just because all others have an argument? Nowadays, the uniform signature could be (Object... objs) which would, e.g., permit you to write count() without the dummy argument. Others, such as sum, average and especially min and max could easily handle more than one argument. Not a bonanza, but being general is not a bad thing...
