Abstract:

Rhombus is a new language that is built on Racket. lt offers the same kind oflanguage extensibility as Racket itself, but using traditiona (infix) notation. AlthoughRhombus is far from the first language to support Lisp-style macros without Lisp-styleparentheses, Rhombus offers a novel synthesis of macro technology that is practicaand expressive. The most significant departure from Racket, apart from the shift awayfrom parentheses, is the use of multiple binding spaces for context-specificsublanguages. For example, expressions, pattern-matching forms,and regularexpression constructions can use the same operators (with different meaningswithout creating conflicts. Rhombus includes support for programmers to create theirown new spaces and sublanguages.
