Corrected.
Never realized public: was implied.

Not much to add but I enjoy reading 'idiomatic' D content - coming from C++, I feel like I'm often not writing my D code like I should be. Thanks for the extra resource.

I saw recently (at last in this thread: http://forum.dlang.org/thread/tdfydchrairigdlgtyum@forum.dlang.org#post-qakiogaqvmiwlneimhgu:40forum.dlang.org) that many users use
----
key in aa ? aa[key] : ValueType.init;
----
instead of
----
auto ptr = key in aa;
ptr ? *ptr : ValueType.init;
----
which is more economic.
Maybe you can add it to your list:

----
import std.stdio;

void main() {
	immutable string key = "foo";
	immutable string[string] arr = [key : "bar"];
	
	if (auto ptr = key in arr)
		writeln(*ptr);
}

mea culpa. i completely forgot about that feature of `alias this`, and was pretty sure that the code above is invalid. i never bothered to really check it. sorry.

we actually can pass "extended" struct as original one, as Artur shown, but i believe that "extending" is still better.

p.s. you forgot to fix TOC, which still reads "struct inheritance".

p.p.s. maybe it's worth adding Artur's code sample[1] too, to show that "extended" structure can be passed to functions which requires original one? it's not obvious, at least for me. ;-)

I didn't knew alias this does object slicing. Will add it.

Sorry for the off-topic noise, but where will you be publishing your articles since Dr.Dobbs has closed?

Sorry if you have answered this elsewhere.

It's a good question. Dr. Dobb's has graciously given me permission to republish them, and I'll post them on http://digitalmars.com/articles. As you can see, I've already done a few of them. Lots more to go.
