I agree, if you want to learn something, you have to spend your time and focus on it. There is really no other way. I can accept it can be more digestible for many if it is packaged nicely in method X. Helping people learn is a very noble goal, but it should come with a fair warning there is no shortcut in understanding.
Coming to think of it same for OO. All those silly Dog is an Animal examples spring to mind.
