Congratulations! Any project that can get rid of moc is a big

with their Qt replacement:

Nice! I've never heard of them, interesting how they proved the
moc maintainer partly wrong.

BTW, what do you think about DMD's recent advancement in this
area? Can you reuse some of this work for Calypso? When do you
think you'll be ready to start upstreaming some of your work to
LDC and/or DMD?

Most of Calypso lives independently from the C++ support in DMD,
and instead queries Clang whenever possible on C++ matters.
It was actually catching C++ exceptions some time before DMD
(https://github.com/Syniurge/Calypso/tree/master/tests/calypso/eh), has no C++ multiple inheritance layout issue since that's handled by Clang, and the only way extern(C++) affects Calypso is by not reverting the order of function parameters so these functions can be correctly called by C++ code (function pointers, overridden virtual methods), and if I understand correctly this is only necessary because there's a discrepancy between DMD and what the docs say: http://forum.dlang.org/thread/zogygbvfszssudpae...@forum.dlang.org?page=2
When do you think you'll be ready to start upstreaming some of
your work to LDC and/or DMD?
My big concern is the switch to DDMD. It seems that the
transition is going pretty smoothly for LDC, but what about
Calypso's extensions to DMD? Calypso classes deriving from DMD
ones will have to be converted to D and those classes happen to
sollicit Clang's C++ API a lot, so I'm counting on C++ Calypso to
build D Calypso meaning it has to be pretty solid at that point
to support both Clang and LLVM.
Anyway as long as both LDC and Calypso haven't both caught up
with DDMD it's probably too early for upstreaming.
The downside is that Calypso is marginalized, I don't get many
testers (<- euphemism, only wilsonk helped a lot and right now
I'm about the only one testing). The neglecting of MSVC, the
"still experimental" label and the lack of releases probably
don't help in that regard. It's not a big deal though since I
have enough on my hands, coming next is the LDC 0.17 merge, and
rework on the PCH generation that should increase the speed 3x
according to cachegrind.
