One of the first things I'm looking at in Go and Rust is compatibility with C. I haven't used D, but this page makes it look as good or better from that perspe

  I can. I've written D interfaces to vendor-supplied C and C++ SDKs and for an open source C library (libusb). We're using this at work. For C, it's relatively easy and mechanical to translate by hand but https://github.com/jacob-carlborg/dstep https://github.com/jacob-carlborg/dstep makes starting trivial. For C++, I had two cases- one was easy as that vendor provided a C handle and function call syntax while the other required doing a C shim (facade) to wrap up the object. I didn't find SWIG to be useful but did examine its output to get ideas. The built-in unit testing in D is very handy.

  It seems Rust and D have very very similar C FFIs, see http://doc.rust-lang.org/book/ffi.html http://doc.rust-lang.org/book/ffi.html . https://github.com/crabtw/rust-bindgen https://github.com/crabtw/rust-bindgen is a tool in the vein of dstep. (Rust has the advantage of having no runtime beyond what C needs unlike D with its current garbage collector, so FFI, especially exposing a C interface, is likely somewhat simpler.)
