Dude we're running unrestricted recursion and closures on GPUs! If that's not cool to you, I apologize, but that mind-blowingly cool to me, and I wanted to share it, even though the codegen is still initial. Hell I was actually going to publish it with the interpreters only, but I still coded an initial compiler because I thought people would like to see where it could go :(
The closure part was when I had to stop for a moment and go "wait, really?! ... COOL!" and I'm definitely going to try and remember to check back every so often (emphasis on 'try' given I have a brain like a sieve but still ;).
