I agree, it certainly didn't seem to be a major consideration early on, but
I don't think any decisions yet made prohibit it from being well suited.
If as you say, there is some focus to generate interest from the game
community, it would be really nice to have a few binary GDC cross compiler
distributions available (for windows, linux users never have problems
building the toolchain themselves). ARM/PPC, maybe MIPS toolchains hosted
somewhere on the website might really help encourage some people get
started, and I'd love to spend some time on the standard libraries for
these platforms.

I appreciate the attention to floating point detail made in D, and this
isn't incompatible with gamedev, but making standard ints compromise basic
hardware implementation just won't fly.
Compile time flag maybe to enable integer exceptions perhaps, or a special
mode like you say...
