My arc repo with keyword args and generic functions: http://github.com/akkartik/arc

Now I'm working on a small, thoroughly-tested language with an emphasis on readability: http://github.com/akkartik/wart. Code sample:

  def (fact n)
    if (n = 0)
      1
      (n * (fact n-1))

  ; Alternatively
  def (fact n)
    (n * (fact n-1))
  def (fact n) :case (n = 0)
    1

Key features: first-class macros (fexprs) also open to extension, pervasive python-style keyword args, it can deduce parens from indentation (but lisp-with-parens will always work), and support infix operations without compromising macros.
