I don't understand. When I say, in Ruby, `"hello".upcase`, I'd say I'm expressing a concept, and a whole lot of nitty gritty - memory allocation, object instantiation, method lookup, etc, is being "filled in" for me. This works because the code I type still expresses exactly what I want. The thing the computer can't do for me is specify exactly what I want. Are you looking for more of the same, or some "guess what I want"?
