Hands down, it's D's shorthand array operations. int[] a = [1, 2, 3]; int[] b = a[] * 3; assert(b == [3, 6, 9]); a[] += 2; assert(a == [3, 4, 5]); int[] c = a[] + b[]; assert(c == [6, 10, 14]); T

I'm really glad you mentioned the concurrency problem from day 18, because this was one of those personal "eureka!" moments I had while learning D. I had no idea that concurrency could be so simple, and this is not even havin

>and till fairly recently it wasn't a community project, but a one-man work All of D except the backend was open-sourced in 2011, I'm pretty sure. Even before that, Walter Bright accepted patch submissions.

D's syntax isn't quite as nice as, say, Haskell (which strongly depends on preference anyway), but it has all the necessary tools to write strongly pure, referentially-transparent functions. There's the `pure` and `immutable`

>Nothrow and Pure are not part of the type signature of functions Actually they are. Take a look at this example: void main() { int delegate(int) @safe nothrow @nogc pure f; //This looks like something bad is happenin

I find that kind of ironic. I know there's a lot of people that love Go and it's a solid language, but I personally see it as the ultimate blub language.

I saw this in theatre and instantly knew something was off with his face. It was such a disturbing feeling, made my brain question whether everyone else in the movie was CG as well and it took awhile before I was able to see the other actor

I'm surprised the author didn't mention the connection between Kong (孔) and Confucius, as Confucius' family name was also 孔.

Ah, I see. I'm assuming then that Rust generics are not generative templates like C++/D, but closer to Java/C#.

As I understand it gaming enthusiasts regard games as being intrinsically art, with no need to "prove" that they can be. Every game from Pong to Call of Duty is a work of art. This whole discussion around whether games are art or

Chinese sentence structure is in many cases identical or very similar to English, and follows the same general word order, Subject-Verb-Object.

Perhaps you should do some research on the subject before making such an ignorant statement.

People often say this because D has many features that allow it to be almost as flexible as the various scripting languages while still being compiled and statically typed. I don't bother with bash/cmd nowadays as D can easily fil

D is what you get if C married Python and the resulting baby was adopted and raised by Lisp and C#.

Yes, this page is quite dated. It dates from the time of D1 (though much of it is still correct).

Where did this myth that Option types are the "solution" to nullable references come from? That's got it perfectly backwards. The solution to nullable references is to remove them from the language; Option is just a means for

I never use anything else anymore for personal projects, unless I absolutely have to due to missing a certain library. A well-known phenomenon in the D community is that it "spoils" you such that when you have to use another langu

"How to remove null checks and then add them back again as a library feature." The difference being, of course, that having an Optional type forces you to check if it's null or not before getting at the underlying object.

I started learning D in 2012, coming from a Java/C++ background. One thing that I've learned over the past 3 years is that D is one of those languages that completely changes your perspective on some aspect of language design (for
