Over the weekend I started hacking around with #TruffleRuby and it's as cool as it seems like it would be. I have done plenty of JRuby in the past and I like it quite a bit. But the debugging and profiling tools on #GraalVM are second to none. And some of the interop is definitely easier... plus the ability to use C extensions! This is the little project i'm building to test it. https://github.com/relistan/shorten-truffle . Will blog something when I've spent more time at it.
