You don't say this specifically in your question, but it seems that when you say DSL, you mean Internal DSL?

Internal DSLs are great, but fundamentally you're always limited by the syntax of the language you're trying to use. Scala is a particularly good language for writing an internal DSL, because it has a simple and flexible syntax. But it's not infinitely flexible.

Other avenues you might want to explore might be:

  1. Choose a different symbol instead of ".". Scala can support Unicode identifiers, so if you fancy going down that road, perhaps you could use "∙"?
  2. Create an External DSL instead?
