Interesting article, though the title should perhaps be `How not to design a Bad DSL` since the vast majority of the advice is apparently what NOT to do.
If the no-go space is larger and easier to fall into, it makes sense to have a more detailed danger map. It might stop a lot of folks from even taking the journey, which unlike real journeys is proper choice. If you are making a DSL for your own enjoyment, don't transmute your joy into someone else's pain. If end users have real issues that your DSL will solve, by all means, make it.
