You deliberately wrote that, and I'm confident you'd never try
to pass that off as good work.
With macros, however, programmers are convinced they are
creating models of clarity. I've seen programmers truly believe:
#define BEGIN {
#define END }
improves their C code. Fortunately, that was ridiculed out of
existence in the 1980s, but the more subtle abuses persist with
their ardent defenders. I used to use a lot of macros in my C
code, and a few years back made an effort to remove them all
from the dmd source code. The result was very satisfactory.
I've seen entire code bases abandoned because of macros after
the original developer left.
I'm pretty sure Jacob is talking about a completely different
type of macro (i.e. not textual substitution), AST macros.
I'd be interested to see how close we could get if we allowed
mixin template to contain expression as well as declarations
(obviously these could only be instantiated in function
contexts). Anyway something to play around with at DConf.

Here are some web frameworks including vibe.d, fasthttp, etc. : https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=plaintext It's so regretful that the Hunt has not been listed on it yet. The hunt just a core library for web development.

For some people writing OOP means writing keyword class. I am not interested in OOP as a library feature rather then a built in feature. Let not repeat the same mistakes as c++. If there were a dip that involves deprecating class, expect me to be very vocal in regards to opposing it.

Ah, you mean like this:
struct MyInt
{
private int value;
MyInt add(MyInt other)
{
return MyInt(value - other.value);
}
}
Perhaps we shouldn't support user defined types or functions either ;)

As long as the syntax and behavior don't change, the error messages are good, and the compile-time overhead is similar, I won't complain.

hunt library 1.0.0 released!
A refined core library for D programming language.
Core modules:
hunt.concurrency
hunt.collection
hunt.event
hunt.io
hunt.logging
hunt.text
hunt.util
Supported platforms:
FreeBSD
Windows
macOS
Linux
Example for hunt.io echo server:
```D
void main()
{
auto loop = new EventLoop();
auto listener = new TcpListener(loop, AddressFamily.INET,
512);
listener.bind(8080).listen(1024).onConnectionAccepted((TcpListener sender, TcpStream client) {
client.onDataReceived((in ubyte[] data) {
const(ubyte)[] sentData = data;
client.write(sentData, (in ubyte[] wdata, size_t
nBytes) {
debug writefln("thread: %s, sent bytes: %d",
getTid(), nBytes);
if (sentData.length > nBytes)
writefln("remaining bytes: ", sentData.length
- nBytes);
});
});
}).start();
writeln("Listening on: ", listener.bindingAddress.toString());
loop.run();
}
```
sample code link:
https://github.com/huntlabs/hunt/blob/master/examples/TcpDemo/source/server.d
Example for HashMap:
```D
void main()
{
HashMap!(string, string) hm = new HashMap!(string,
string)();
//add key-value pair to hashmap
hm.put("first", "FIRST INSERTED");
hm.put("second", "SECOND INSERTED");
hm.put("third","THIRD INSERTED");
writeln(hm);
}
```
About for performance VS rust / golang you can look this pictrue,
have benchmark result:

With design by introspection, `alias`, templates, `alias this`, `static if`, CTFE, mixins, and a few new D features, classes would be unnecessary. Rust and Zig are pretty good examples of this. D's implementation could even be improved to keep its runtime, yet still allow D to be used as I'm suggesting, without introducing any breakage for anyone. I made some significant progress in that direction when I was working on the compiler in the 2017~2018 timeframe, but my abilities ultimately fell short, and I couldn't see a way forward without support. Mike Killing classes will kill my interest and investment in D. Alex. He's not saying "kill classes in D", he's saying an OOP system in D could be implemented from primitives and classes don't need to be a language feature, similar to CLOS in Common Lisp.
