This is fantastic news. I'm eager to give it a whirl so I cloned and 
attempted to build but encountered the following issues:

huekomundo:Digger andrewedwards$ rdmd --build-only digger
ae/sys/signals.d(55): Error: undefined identifier SIG_BLOCK
ae/sys/signals.d(65): Error: undefined identifier sigtimedwait
ae/sys/signals.d(60): Error: undefined identifier SIG_SETMASK
ae/sys/data.d(521): Error: undefined identifier pageSize

I'm using DMD v2.065.0 on Mac OSX 10.9 (Mavericks).

Thanks,
Andrew
