It bugs me too, though I have done it. I think the right answer of why it is odd is because writeln is void. As soon as it is placed on the end the chain is broken and you can't expand on it. This is no different from any other "sink" that consumes a range: someSource .map!foo .filter!bar .splitter(baz) .each!quux; `each` returns void [1], so using it ends the chain. But that's not a problem, because the whole *point* of using `each` is to consume the range. [1] Not exactly, but close enough.

If you're writing idiomatic D code, why not not all in on it? I agree with Adam and others on this. My reasoning is, writeln's first parameter is not special compared to its other parameters. In other words, I can't see writeln as a special operation on its first argument. Except, when there is just one thing... Meh... I don't like it. :) Ali

Me too. It gives me the same creepie-feelies as when people write
writeln(x) as:
writeln = x;
Actually, D's lax syntax surrounding the = operator gives rise to the
following reverse-UFCS nastiness:
// Cover your eyes (unless you're reverse-Polish :-P)! and don't
// do this at home, it will corrupt your sense of good coding
// style!
import std;
void main() {
writeln = filter!(x => x % 3 == 1)
= map!(x => x*2)
= [ 1, 2, 3, 4, 5, 6 ];
}
// Output: [4, 10]

DIP 1029--Add throw as Function Attribute--Formal Assessment
Now that our new DIP rules have been announced, I'm going to get the DIP process moving again. And the first thing on the list is the announcement that DIP 1029, "Add throw as Function Attribute" has been accepted. https://github.com/dlang/DIPs/blob/master/DIPs/accepted/DIP1029.md The rationale is in the DIP's Review Summary, but I quote it here for convenience: "This DIP was accepted with no request for revision. The Language Maintainers felt that arguments suggesting alternative syntax, such as @throw or throw!bool, are not persuasive. The motivation behind @ in attribute names is to provide an alternative to the introduction of new keywords. However, throw is already a keyword, and adding @throw would introduce an incongruity with nothrow. Leaving them both as-is is the simplest approach. throw!bool would render nothrow redundant and is inconsistent with the existing set of built-in attributes. Also, there were no strong objections to the proposal itself. Although some objections were raised to the introduction of a counter to nothrow alone as opposed to a broader proposal encompassing all similar attributes, the Language Maintainers see no problem. This DIP is focused solely on the obvious application of the existing throw keyword to its new role. Any larger changes to attribute syntax are beyond its scope."

Great article. I assume you didn't chained writeln by purpose,
same for import std?
```
import std;
int[] evenNumbers(int[] numbers)
{
return numbers.filter!(n => n % 2 == 0).array;
}
void main()
{
[1, 2, 3, 4].evenNumbers.writeln;
}
```
Kind regards

Oop! Chaining the writeln too could have increased the wow
factor. I didn't see that.
