Bjolang is a Lisp for .NET. It has types that are inferred, unions that are
matched exhaustively, traits, hygienic macros, and bjoroutines, and it
compiles to C#.

@codeblock[#:lang "bjolang"]|{
(import (std prelude))

(type (: Shape (Union (: Circle double)
                      (: Rect double double))))

(: area (-> Shape double))
(defun (area shape)
  (match shape
    ((Circle r) (* 3.14159 (* r r)))
    ((Rect w h) (* w h))))

(defun (main args)
  (loop (:for s [(Circle 1.0) (Rect 2.0 3.0)])
        (:do (println #"area: ${(area s)}")))
