auto result = hash.finish();

From the examples where this appears, I have absolutely no idea what 'result' could possibly be and what I can do with it, and you're forcing me to go and dig further for that information (waste of time).

Surely there would be no harm in just writing the type there for clarity?

I'd personally like to see auto abolished, or at least heavily discouraged for the sake of clarity from code examples throughout the docs. I'm constantly having to chase up what auto's may resolve to when reading examples >_<

You may argue this demonstrated un-idiomatic code, and my trouble is due to inexperience; I ask, who is most likely to be reading docs?
