I like seeing stuff in this area -- C is great but feels unnecessarily hobbled by the long edit/compile/run cycles. My own attempt at solving this right now is a C variant that's amenable to SLIME-style incremental development, and I'm having fun doing it, but it'll be a while before it's useful. This linker idea is really smart. Being able to drop it in to existing C projects is a big win.
