Does anyone else feel that iterator syntax sugar is a must have in a modern language?

Question

I work with C# professionally and I write code like this all the time.

private IEnumerable<Something> GetAlotOfSomething()
{
    if (somethingA.IsReady)
        yield return somethingA; 
    if (somethingB.IsReady)
        yield return somethingB; 
    if (somethingC.IsReady)
        yield return somethingC; 

    // ... More complex logic
}

var specialSomethings = 
    GetAlotOfSomething()
    .Where(s => s.IsSpecial); 

Then one day I have to write a bit of VB6 or JScript and I end up writing so much boilerplate just to get things done. Anyone thoughts?

Answer 1

Iterators (generators etc) are certainly great features that I use a lot. I don't qualify them as necessary, but I will certainly choose languages that have them when I get a choice.

Answer 2

They're... Handy.

But you can always just write your own if necessary. The big wins come from standard library / framework support.
