In his code I did notice he doesn't use destructing very much

hi community,
i decided to create a (small) game in clojure to get a bit of
non-theoretical experience. i'm pretty much a clojure noob (only

i am used to less concrete programming. i ask my tools to do the

dependant on mutable state external to he function, in the most
part.
I am agreeing with you, and find these real world experiences
incredibly useful.

hi there,
i stumbled over two odd things
1) - and - have the same source code. why is that?
