Dylan

In my CS course, we are currently useing a particular implementation of
Dylan called NOODLLE.  It is a subset of the 1992 specs, not the most
recent.  In NOODLLE Dylan, the program is as follows:

(define (hello ) (method () (print "Hello, World")))

The looping version is:

(define (hellol )
      (method ()
            (print "Hello, World")
            (hellol)
      )
)
