A lesson to help beginners dodge various syntax traps

With exercises that may be a little too frightening...
Should we have this so early? Should we have it at all?

to allow a complete beginner to take advantage of the current
tutorial, yet I'm not convinced this is a good idea to draw
attention on this topic.
