I'm really excited to see how rhombus turns out, and can't wait too see how they resolve some of the hairier design decisions around building a form-based language with implicit forms. (Shrubbery seems interesting.)

As an aside, I'm working on a different new programming language that supports language-level programming through a macro/effect system (and doesn't use s-expressions). In practice, Macro systems work well on any language that has the concept of 'forms' (see: Homoiconicity isn’t the point)
