I don't mean "morally higher" ;)
Just more concise and easier to grasp, same as VIEW vs. TABLE + ON xxx
DO INSTEAD rules.
With INSTEAD rules you can do more than a VIEW does, but when all you
want is a VIEW, then it is easier to define a VIEW, thus VIEW is a
higher level construct than TABLE + ON xxx DO INSTEAD
That is the same way that C is "higher" than ASM and ASM is higher than
writing code directly using hex editor.
