Meson is a very interesting merge of ideas from SCons and CMake, but it
has some serious annoyances, e.g. no unity build for D. I still use
SCons a lot, but there is apparently a lot of negativity about it as a
build system within Debian packaging.

Creating packages, some, a long time ago. Being involved in the Debian
process, none – other than bug reporter.

I'll try building an equivalent for dinotify since it is a single
module system.

I doubt I will be able to be at a key signing session to collect enough
signatures. But I am happy to do stuff that then gets reviewed and
either passed on or passed back.

OK, that makes a lot of sense. I should have twigged to the "not a
public instance". Hopefully the freedesktop people do something similar
so the GStreamer workflow can enter the modern era.

The general "prejudice" seems to be: DMD is the reference
implementation is a fast compiler but generates not the best generated
code; LDC has a recent D front end, the LLVM backend produces good code
but is slow; GDC is part of the GCC suite so generates good code but
the front end is not as recent a D front end as LDC. I'd say LDC is the
right compiler for packaging, at least just now.

Done and done.

I'll check these out.
