The beauty of D lies in it's holistic approach.
The one unique feature to point out would be CTFE which is not
to be found in other compiled langauges.
constexpr does not even come close since it cannot return
literals :0
CTFE is indeed unique but is it a selling point where people
will talk about. Something that they will experience in there
daily life and say, i can not live without that?
Yes, D's compile-time regex are still the fastest in the world.
I've been benching it recently for a marketing-oriented blog post
I'm preparing for the official D blog, std.regex beats out the
top C and Rust entries from the benchmarks game on linux/x64 with
a single core:

D comes in third on Android/ARM, but not far behind, suggesting
it would still be third on that list if run with a bunch of other
languages on mobile. Dmitry thinks it might be alignment issues,
the bane of cross-platform, high-performance code on ARM, as he
hasn't optimized his regex code for ARM.
Its part marketing, part unique features, part giving people
confidence by having a big name attached to it. A lot of
languages really are so much the same ( fast compiling, single
deployment, multi platform, ... ), that it becomes harder to
stand out with features that the end user cares about.
Recently been doing a bit of Pascal programming. Ultra fast
compiler, low memory usage ( No GC ), cross compiler with
massive platforms support, there own cross platform GUI (
Lazarus ). And yet they have the same issue. Pascal does not
stand out despite being a mature and easy fast, efficient
language. But it did get included in that article ;)
D is technically C++ replacement and yet, C++ has been losing
massive market shares but D has not been enjoying much from
that loss.
Frankly, i am also a bit lost of ideas as to what can D stand
out. Its almost like D is going to Pascal route. People use it,
it great, but beyond the core audience, its hard to reach out
to others.
The pitch is that you can write very fast code quickly and
easily, and make it the fastest in the world if you spend some
time profiling and optimizing. At the end, you'll have code that
you can actually read easily and aren't scared to modify because
you're not sure you understand how it works. And all this
without struggling with C's primitive features or Rust's borrow
checker.
Is the dream fulfilled? No, D still has plenty of rough edges
and gaping holes:

But with tech nowadays, you need a good foundational design
before all else. Yes, someone else may get out of the gate
faster with the bicycle they built out of spare parts, but once
you get the Millenium Falcon going, it will blast by them. ;)
