"body" keyword is unnecessary

A bit off-topic post:

I first hit "body" when porting the nbody benchmark test from the 
Computer Language Shootout to D.

http://shootout.alioth.debian.org/u32/performance.php?test=nbody#about

I wanted to write things like:

foreach (ref body; bodies) {
	body.x += dt * body.vx;
	body.y += dt * body.vy;
	body.z += dt * body.vz;
}

BTW, in that benchmark D, with my clean implementation, would perform 
similar to "Clean", about 1.7x slower than the fastest, Fortran. That is 
with GDC and all optimizations. DMD a bit behind with a 2.1x elapsed 
time. Both are behind Java, C and C++.
