That's not how you see it when you're learning though.

It's more like, I can imagine someone asking these:

1. Why the heck do I see "hasMember" twice?
2. What does this have to do with enums?
3. Where is anything getting "returned"???
4. So you mean templates are THINGS?? I thought you needed a 
template SOMETHING, like a template struct, template function, 
5. What the heck is TypeTuple!()? Where's the blueprint?
