[$] Flexible metaprogramming with Rhombus

Lisp-like languages have historically led the world in metaprogramming and flexibility. While many modern languages have adopted the idea of macros, Lisp-like languages such as Racket have continued pushing the envelope, attempting to make macros as easy as possible to incorporate into everyday programs. On the other hand, Lisp's minimal, parenthesis-based syntax can be hard to adapt to — to the point that Lisp is sometimes said to stand for "Lots of Irritating Silly Parentheses". Rhombus is a new programming language that aims to have the best of both worlds, marrying Racket's metaprogramming capabilities to a simple Python-like syntax and reasonable standard-library defaults.
