I love munificent's opinions on programming langugaes (wish he'd never given up on magpie...), and I can't wait to try this one out.
Unfortunately it doesn't build under GCC on linux right now, so use clang if you want to try it out.
For those not familiar with munificent, you may recognize his moral conviction from one of his previous creations, Vigil: https://github.com/munificent/vigil
