The two efforts are independent, and the main issue with Calypso's approach: it's tied to LDC, LLVM and Clang. Although I had a slight hope that the approach would get recognized as allowing perfect interfacing with C++ incl. things unthinkable with the « from scratch » approach (like C++ template instantiation) and give D an edge that would probably be sufficient to make lots and lots of people switch from C++ to D, as long as DMD is there and a GDC/GCC version isn't proved feasible there's no question about whether this approach should get officially endorsed or not, and nevertheless the current efforts towards better C++ support in DMD should still yield important results.
Calypso will exist as a LDC plugin, and yes code using Calypso features will only be build-able by LDC+Calypso.
As I see it the goal here is to spearhead a working Qt <-> D interaction, but how would this be used in production? Would Calypso simply be run to generate bindings
The goal of Calypso is to make any C++ library of any complexity usable in D straightaway, and there's no binding involved.
moc was a barrier for Qt because it only parses C++ code, and Qt's C++ API can hardly be used without the code moc generates.
