ZLinq: A Radical Optimization and Extension of LINQ

ZLinq is a .NET LINQ library that dramatically improves LINQ performance through clever architecture and optimization strategies. It introduces the `IValueEnumerator` interface, replacing the traditional `MoveNext` and `Current` with `TryGetNext` to reduce method calls. Furthermore, it supports `Span` and SIMD operations, and provides LINQ support for tree structures like JSON and Unity's GameObjects. ZLinq's optimizations aim to minimize allocations and method calls, resulting in faster processing, especially beneficial when dealing with large datasets or performance-critical scenarios.
