At https://wiki.dlang.org/Talk:Deimos I propose to change Deimos rules:

---
Can we lessen the rules to allow linkage to our D binary for additional D modules (not for the module which does plain C linkage)?

The idea to avoid D linkage was probably wise, but why to require it for every module? We could allow to compile and link additional modules (such as object-oriented wrappers above the linked C code).

Your opinion?

You can provide D code as a separate package.

I tried to answer this by clarifying https://wiki.dlang.org/Deimos#Translation just now.

See the first item under "Translation", especially the rationale.

Hope this helps.
