What is a “yield return” equivalent in the D programming language?

Question

Here is a simple generator in C#.

    IEnumerable Foo()
    {
        int a = 1, b = 1;
        while(true)
        {
            yield return b;
             


        

Answer 1

See here; example excerpt below:

module main;

import std.stdio;
import generators;

void genSquares(out int result, int from, int to)
{
    foreach (x; from .. to + 1)
        yield!result(x * x);
}

void main(string[] argv)
{
    foreach (sqr; generator(&genSquares, 10, 20))
        writeln(sqr);
}
