D is a weird one, because it has been lurking around for at least a decade and a half without really picking up the kind of steam and hype that later entrants have. I remember dabbling with D for game development way back in high school, as a friendlier alternative to C++.

Well, Standard ML is a weird one too in that sense (lurking around for a couple of decades without picking up steam (outside academia?)). Languages having type inference and modules designed into them seems to have a good chance to live long.

D excluded itself from being C/C++ killer by having a GC. I know they've backtracked on that, and the -betterC subset of D looks interesting, but it's a bit late for that.

Only to the GC hating crowd.

Unreal and UWP/COM developers are perfectly fine with writing C++ code with a GC around.

[pornel]

If GC & runtime is on the table, then there are many nicer languages you can use (Go, D, Swift, Kotlin). I assume that the C and C++ users who haven't switched yet are largely the "GC-hating" crowd that can't.

COM and other refcounted ones get a pass. But I'm surprised that Unreal gets away with a mark-and-sweep GC. Perhaps because it's only required for UObjects, and the rest of the codebase can still easily avoid using the GC? You can even cause use-after-free bugs on UObjects, if you want to.

Isn't Swift also refcounted?

[pjmlp]

Reference counting is a GC algorithm, as per CS curriculum.

Try to broaden your horizons.. I work in telecoms only one step away from a FPGA, a 1ms pause would be a critical bug report..

[pjmlp]

My horizons are already broaden.

You can also try to broaden yours.

Will this work for you? I guess most likely not, and you really cannot afford any kind of delay, where even a C++ virtual call would be considered a bug, given the 1ms delay.

The point being that only a very tiny population has such requirements, just like barely anyone writes applications 100% fully in Assembly.

[renox]

I'll look at your links but to answer to your question: yes virtual functions are not accepted in the code.

[adamnemecek]

I think that part of the reason it didn't pick up is because it was made during an era when talking about the problems of C++ was brushed aside with "learn to program kiddo".

[catach]

I suspect we are at least partially still in that era.

Success is often a matter of time. A good idea too early is the wrong idea kind of thinking.
