My post was not about betterC, it was about the super easy interoperability of C and D. This capability has been in D for several years now, and has been very popular as there's no longer a need to write an adapter to use C source code. The ability to directly compile C code is part of the D compiler, and is known as ImportC.

One interesting result of ImportC is that it is an enhanced implementation of C in that it can do forward references, Compile Time Function Execution, and even imports! (It can also translate C source code to D source code!)
