Another good feature:

Interfacing to C is somewhat easy at least for the basics. (I haven't looked at advanced cases yet, but maybe someone else can comment on that.)

This is a great feature IMO, because it allows you to (re)use the huge number of existing C libraries out there.

Here is a simple example:

Calling a simple C function from D - strcmp:

There's a handful more small examples of a few things D can easily do, here on my blog:

(And of course, there are many more at the DLang tour site - https://tour.dlang.org/ )

Also, there are a few good videos about D (alone) and being discussed along with other languages, at my blog's DLang posts link above.

I'll just put some post titles here to give a quick idea:

Simple parallel processing in D with std.parallelism

Using std.datetime.StopWatch to time sections of D code

Read from CSV with D, write to PDF with Python

Command line D utility - find files matching a pattern under a directory

min_fgrep: minimal fgrep command in D

num_cores: find number of cores in your PC's processor

Func-y D + Python pipeline to generate PDF

file_sizes utility in D: print sizes of all files under a directory tree
