I recently stumbled over a very odd source listing on a rather old programming-related site (lost it somewhere in my browser history as I didn't care about it at first).

I think that this is part of a simple (console-based?) snake game.

I searched and searched but didn't find a language that looked somwhat like this. This seems like a mix of Python, Ruby and C++. What the hell?

• What programming-language is the below source listing written in?

Maybe you can figure it out?

my Snake.hasProps
 {
   length
   parts
   xDir
   yDir
 } & hasMethods {
   init: length = 0
         parts[0].x,y = 5

   move: parts[ 0 ].x,y.!add xDir | yDir             # Move the head
         map parts(i,v): parts[ i ] = parts[ i + 1 ]
         checkBiteSelf
         checkFeed

   checkBiteSelf: part

 }

my SnakePart.hasProps
 {
   x
   y
 }

fork SnakePart to !Feed

my Game.hasProps
 {
   frameTime = 30
 } & hasMethods {
   init: mainloop
   mainloop: sys.util.sleep frameTime

             Snake.move
             Field.getInput -> Snake.xDir | Snake.yDir
             Field.reDraw with Snake
                               & Feed
                               & Game # For FPS

 }

main.isMethod
 {
   game.init
 }
