If [1] gets merged we will have a situation where code[2] is
required to interoperate with D's slices from C++. I think we
should have an official repository where such code and
documentation lives (i.e. on the dlang github). This would also
be a good place to have links to other interoperability successes
in D like pyd, dpp, embedr, luad, autowrap etc. and put the D
interoperability story out there, coherently and in one place.
Thoughts?
