Yes, but IME many tutorial presentations on these subjects never get as far as actually building a complete, functional compiler to demonstrate the concepts. Often they use some form of interpreter instead, which means they can use structures in the interpreter's implementation language that somewhat reflect the run-time structure of the implemented language using the analogous language features.
Well, it makes sense for tutorials to use what they can to simplify the bits they're not focusing on, but certainly implementing a construct by mapping it into an identical construct is not going to be terribly informative as to the workings of that construct. That may be totally appropriate if the focus of the tutorial is on the parsing or such, but it sounds like that sort of tutorial (of which there are many, and which are perfectly useful to other purposes) are not what you are looking for.
