Duby is a Ruby-like static-typed language with local type inference
and not many bells and whistles.  The primary motivation was to have a
Ruby-like language to implement parts of JRuby.  Duby looks and feels
mostly like Ruby but compiles to tight JVM bytecode on par with what
you'd get from compiled Java.

def fib(a => :fixnum)
  if a < 2
    a
  else
    fib(a - 1) + fib(a - 2)
  end
end

puts fib(45)
