I have a question about control flow of the overall system. Note that I haven't actually run this or debugged it. Or frankly, thought about it for more than a minute or two. Its more of an architectural question.

So in dragon.clj there's a case statement to execute commands in the translate function such that the command to go down or left in an abstract calculated sense is implemented as hitting a virtual down or left keyboard key.

What happens if you have to go down AND left?

I was just thinking why not pass a Clojure list to the translate function and when list contains a down it hits the virtual s key AND if the list contains a left command it hits a virtual a key, then you could wiggle "down-left" at the same time.

I mean, obviously it works and sometimes architectural decisions have no technical reason and are arbitrary, which would be perfectly OK. I was just idly curious.

Clojure is cool, like programmer catnip, so I had to look at it.
