If you've got problems using D that should be fixed:

1. File bugzilla issue for them. Issues not in bugzilla don't get fixed.

2. When talking about the issue, provide a link to the bugzilla issue so we know what you're talking about and know what the current status is.

3. If you have a laundry list of issues that are important to you, keep a list of bugzilla issue links to them. Then, when you are asked about what problems you're having, cut&paste that list.

Bring them up now and then.

It's that simple!

How frequent is "now and then"? Like, once a month? Once a year?

Ideally, you would be prioritizing issues based on severity and impact. If you only fix the issues that people nag you about, you risk leaving serious bugs unattended.

Anyway, here are some personal favorites:


1) The DIP 1000 implementation has a glaring accepts-invalid bug with `pure` functions.
https://issues.dlang.org/show_bug.cgi?id=20150

In my opinion, this one is a blocker for DIP 1000. And unfortunately, it probably made DIP 1000 look better than it is.


2) "bool can be both true and false"
https://issues.dlang.org/show_bug.cgi?id=20148

This one is just silly.


3) DMD's codegen for the BT (bit test) instruction is all kinds of wrong.
https://issues.dlang.org/show_bug.cgi?id=18750

A testimony for the questionable quality of DMD's backend.


4) "import doesn't verify module declaration"
https://issues.dlang.org/show_bug.cgi?id=15086

This accepts-invalid (and arguably wrong-code) issue had some lively discussion years ago. There was a PR, the issue was closed as invalid, it was reopened. And finally it was forgotten.


5) std.stdio tries converting between different UTF variants, but fails horribly.
https://issues.dlang.org/show_bug.cgi?id=18789 and
https://issues.dlang.org/show_bug.cgi?id=18801

I tried fixing this one but got stuck when I couldn't reproduce the failures on Windows that the auto-tester shows.

If you start annoying people, then it's too often.

Everybody's idea of what is important and what is not is different.

Nah, it's not silly, it's just that DMD's backend produces code that exhibits quantum uncertainty:

-----------------
bool schrodingersCat() @safe {
	union Box { bool b; int spin; }
	Box u;
	u.spin = 2;
	return u.b;
}
void main() @safe {
	import std.stdio;
	bool b = schrodingersCat();
	if (b) writeln("alive");
	if (!b) writeln("dead");
}
-----------------

Output:
-----------------
alive
dead
-----------------

:-D

Unfortunately, LDC's backend seems a lot more classical, as the above code produces this output with absolute certainty:

Output:
-----------------
dead
-----------------

Truly, DMD's backend is in the bright future of strange and wonderful quantum effects, whereas LDC is clearly still stuck in the antiquated classical past. ;-)

Actually I'm wondering if we can have a web poll widget somewhere, so people can vote on the priority of bugs / features / DIPs?

Better be on the front page of https://forum.dlang.org ?

Polls are a dime a dozen, but rarely lead to any actual change. What actually makes a difference is someone who's willing to put in the time and effort to actually work on these bugs, or at least dig further into them to obtain more useful, actionable information.

Just sayin', from past experience.

For even more quantum fun:

----------
bool schrodingersCat() @safe {
	import std.random;
	union Box { bool b; int state; }
	Box u;
	u.state = uniform(2, int.max);
	return u.b;
}
void main() @safe {
	import std.stdio;
	bool b = schrodingersCat();
	if (b) writeln("alive");
	if (!b) writeln("dead");
}
----------

With LDC, this code will output either "alive" or "dead" with a roughly 50% probability of each.  So it's a classical observer.

With DMD, however, this code will perceive the quantum superimposition directly and output both "alive" and "dead" every time.

:-D

OK, I'll stop now. :-P

These two posts made me very amused. Thank you.

I just said few days ago: D is fun to work with everyday!

I think if we have a poll widget, this fun bug will surely be top voted :-)

You can already vote on Bugzilla issues.

But what matters is finding someone with the time, interest, and expertise to address each problem.
