Szathmáry László honlapja @ DEIK | DLang / lambda function

(1) without lambda
	import std.stdio; string[] makeFruits() { auto result = ["apple", "kiwi"]; result ~= "banana"; return result; } void main() { const fruits = makeFruits(); writeln(fruits); }

We call a function that has a name. The function returns a list.

(1) WITH lambda
	import std.stdio; void main() { const fruits = { auto result = ["apple", "kiwi"]; result ~= "banana"; return result; }(); // we call it writeln(fruits); }

Here, we define a no-name (anonymous) function (a lambda function), and we call it (notice the () at the end). Similarly to the previous example, it also returns a list that we store in a variable.
