Thanks, Adam!

To elaborate on my second point: if one compares, say, FreeBSD's 
libc [1] with glibc [2] it is pretty obvious that not all 
implementations are optimized to the same degree.

Does it make sense - at least in cerain cases - to provide and 
use a D implementation that is fast on all platforms, instead?
