The simpler - the better.
After reading "D p.l." by A.Alexandrescu two years ago I have found my past dream. It's theory to start with. That book should be read at least two times especially if you have asm/c/c++/python3/math/physics background, and dealt with Watcom/Symantec C/C++ compilers (best to Walter Bright) with very high optimization goal. No stupid questions, just doing things.
That was preface.
Now I have server written in D for C++ pretty ancient client. Most things are three times shorter in size and clear (@clear? suffix). All programming paradigms were used.
I have the same text in russian, but who has bothered russian(s)?
The meaning of all of that is: powerfull attractive language with sufficient infrastructure with future. Just use it.

p.s. I'm excused for my primitive english.

Welcome, Igor!

Your sentiments reflect mine years ago when I first discovered D.  I came from a C/C++/Perl background.  It was also Andrei's book that got me started; in those early days documentation was scant and I didn't know how to write idiomatic D code. But after I found TDPL, the rest was history. :-)

We have a few Russians on this forum, and I can understand some Russian too. Though on this mailing list English is the language to use.

Yes, I agree!

Your English is understandable. That's good enough, I think. :-)

I was a little bit afraid of my missunderstanding in terms of sentiments. You've got me right (I don't quite feel the meaning of that in these non-cyrillic letters:). But what I understand is the path you have walked and what I have in my mind.
Simple example about D: I spent two hours to write a line (borrowed from Python), related with lazy calculations, but finally I got it with deep great thinking, and it was like understanding of Moon alienation from Earth.

Sure, I don't have any doubt of it. I hope to be one of russian understandables here:)

Thank you, Teoh. That is very important for me to hear.

What is your using of D?
For me it is tool to develope other tools.

Yes, I meant 'sentiments' as in опыта, not as in сентметальность. :-)

Great!  Would you like to share the code snippet?

Sadly, I have not been able to use D in a professional capacity. My coworkers are very much invested into C/C++ and have a very high level of skepticism to anything else, in addition to resistance to adding new toolchains (much less languages) to the current projects.  So my use of D has mainly been in personal projects.  I do contribute to Phobos (the standard library) every now and then, though.  It's my way of "contributing to the cause" in the hopes that one day D may be more widespread and accepted by the general programming community.

Sorry, typo. I meant сентиментальности. But I think you understand what I mean. :-)

I used to mean 'sentiments' as "сентиметальность", but "опыт - сын ошибок трудных" (Пушкин) is what realy in behind :)

Sure. We have an array of uint. And we need to get a string of these values in hex separated with ','. In Python it looks like
<code>

     ', '.join(map(hex, array))
</code>


array.map!(v=>"%x".format(v)).join(", ")

Sure. Let we have a uint_array of values. And we need to get a string of these values in hex separated with ','. In Python it looks like

<code python>
     ', '.join(map(hex, uint_array))
</code python>

After 2 hours of brain breaking (as D newbie) I have come to:

<code D>
uint_array.map!(v=>"%x".format(v)).join(", ")
</code D>
Why 2 hours? Because I have started with 'joiner' function and aftewords found out the 'join'.

To my mind there is more simple form for this task in D (about formatting).

Same here.
But my coworkers are not addicted to programming at all :)

I don't hope about "D some day", I'm sure about that (5 to 30 years).
The idea is "I D", not "I C++" :)

I Think there's a bug. When I'm answerring a message, and if my recipient send me the message, and after I press 'send' button, my message is duplicated. Simple bug to repare.

sure ;-)

import std.stdio;
import std.format;
void main () {
  uint[$] a = [42, 69];
  string s = "%(%s, %)".format(a);
  writefln(s);
}
