Looks impressive. I like the fact that VibeD has some competition - it is healthy that way. Good job guys!

Is there an online comparison describing the differences between Hunt and Vibe.d? I'm mainly interested in

- fast incremental compilation,
- high run-time performance and
- expressiveness

In other words, how to most easily get the job done with the least amount of code.
