Net 9.0 LINQ Performance Improvements

C# design team is/was unparalleled

It is relatively easy to find similar capabilities in most languages nowadays, unless one is stuck on Go, C and similar.

Maybe you do simulate some of this using meta programming in ruby but its certainly not 'easy to find'.

And I explicitly left Go out of my list.

yes thats what linq is?

https://learn.microsoft.com/en-us/dotnet/csharp/linq/

"Language-Integrated Query (LINQ) is the name for a set of technologies based on the integration of query capabilities directly into the C# language." With LINQ, a query is a first-class language construct, just like classes, methods, and events.

doing this in java is not LINQ imo

  List<Integer> lowNums = filter(toList(numbers), new 
  Predicate<Integer>() {
        @Override
        public boolean apply(Integer n) {
            return n < 5;
        }
    });

    var lowNums = Arrays.stream(numbers).filter(n -> n < 5).toList();

Which still isn't as nice as LINQ, but this way we've painted the alternative in its best light, not in the light that makes C# look the best.
