Frankly, just saying that you expect people to pay attention and that's why the names aren't typed out seems lazy. If the snippets are as simple as people state then the names won't ever reach the Java style AbstractionFactoryGeneratorSingletonInterface that are difficult to parse due to the name. If they did end up getting that long that'd be more of an indication that the pieces of your code are doing far too many things, or are too complicated of an abstraction anyway for people to be easily able to understand the snippet. Not specifying what you mean when teaching/demonstrating has no benefits in my eyes
