[WIP] An REPL module for vibe.d ?

I found myself needing this while working on a non-web project.
I thought this could be a good addition to ab asynchronous I/O framework, so here it is.
Few questions:

1) Will you want such functionality in the framework ?
2) Will you want it in it's current form ? (Yeah the code is ugly).
3) Any idea of worthy addition ? I think a debug console for HTTP would be kinda cool. Most basic example would be to set the debug level using the console. But I'm a bit short on idea right now, as I wrote it for other purpose.
