F# can almost do the same with C# Object Initializer, but how about Collection Initializer? I’m using fold to call .Add() today but wonder if there’s any better way.

Use case: Class InputMap<V> from Pulumi
Well, for this particular case, I think the API should be improved (e.g. by taking IDictionary<string, V>) but that’s probably another story.
That isn’t possible in F#. I would just suggest that using a plain old for loop would be better than a fold. It’s simpler and more obvious that you’re performing a side-effect
