You should mention that ImportC supports C constructs that are not expressible 
in D, such as _Generic and bitfields. (Although I added bitfield support to D 
recently.)

C interoperability is a major barrier to using D. ImportC is probably the best 
leverage for D among existing initiatives.

The trouble comes when those header files change, you've got to figure out what 
changed and update those hand-translated files. This is a big win for ImportC.
