Ish? If we are talking about "hammer training," then I can see the argument. Teach me about the different hammers and why I would pay attention to the weight and such.

But all too often, the training picks something like "build a clubhouse." And in that, I would expect legit solutions based on specifications of a clubhouse that you are wanting to build.

Language advocates fall hard on this. They will "build a TODO application" to show off part of the language. But end up with an application that can't do what folks would want a TODO application to actually do. It is very frustrating.
