This issue (its a very long read: https://github.com/rust-lang/rust-roa dmap/issues/12 ) on the Rust Roadmap repository indicates that integrating Rust with Bazel and Buck are important roads to traction in the C++/Python circles for Google and Facebook. This may or may not be an interesting thing to try and do for D.

The lesson though is that any form of integration is not done till crates.io is accessible using the build system not Cargo. The inference is that, for D, accessing the Dub repository (and DVCS repositories) from Dub, CMake, Meson, and Scons is the right thing to do. Dub clearly can handle Dub (but not DVCS repositories?).

Experiments with using Dub to fetch and compile packages for SCons – since packages only have Dub specifications, it makes no sense to try and download from Dub and build with SCons – are progressing and show it feasible. The same now needs doing for Meson and CMake.

Can Dub pull packages from DVCS repositories? If not this must be added since this is a crucially useful feature of Cargo for those at the bleeding edge.
