If you need a feel of what the community values (apart from rants), have a look at the forums. https://forum.dlang.org/ D is backed by companies like Sociomantic and Weka.io that operates in high-performance domains.

Went from Delphi to Ocaml to lots of C++ to D. Basically I'm happier with the products I wrote in D so I keep using it. It's an almost schizophrenic language that always says "yes" when you ask if something is possible.

In D this is indeed known only at runtime, one of the decision was that "there should be only one type of pointers". immutable(T) doesn't guarantee it isn't in the GC heap from what I can gather. shared(T) could perhaps

Yes I thought GC write barriers were always implemented with memory barrier instructions. Probably a trap because the same word is used. Still I wonder how they are implemented then.

I meant "memory barriers". Atomics embed memory barriers.

And if I use only a bit of the GC, can I use only a bit of write barriers? Walter Bright was right about segmented stacks, I'm tempted to think he's right about write barriers too.

Let me amend then: "A fast copying collector _in D_ would require write barriers". Of course with other languages you can have GC without that limitation.

by p0nce 10y ago
You can always use less of the GC, but there are no way not to use pointers. For example, I sell products in D which disable the GC completely, I certainly don't want write barriers.

The case against write barriers is pretty simple: the slowness of the GC can be workarounded, while memory barriers cannot. If they are needed, no other way to copy pointer values (which are quite pervasive in system programming).

A fast copying collector for D would require write barriers: using memory barriers everytime a pointer is written. This has a runtime cost. > which runs at every allocation. The article explains in great depth that this is not the case.

Most folks haven't tried D.

That's definately important in France where some important tax cuts depends on your degree.

Damn, I knew I was charging too little. Not only noone is complaining about price, but some explicitely says it's not expensive.

D has no overhead syntax for CTFE, "comptime" is from the context.

This is invalid since nothing in the compiler forces you to remove the .unwrap() so it's safe to assume it will not be done before production. The whole "but this is just for prototyping" is a logical fallacy, as you know we
