### Describe the enhancement requested I have been hand-writing a pile of generic kernels for numerical arrays and wanted to know what would be required to contribute them upstream. So far I have implementations for: - `public static Array Filter(Array array, BooleanArray mask)` - `public static BooleanArray Equal<T>(PrimitiveArray<T> lhs, T rhs) where T: struct, INumber<T>` - `public static BooleanArray Equal<T>(PrimitiveArray<T> lhs, PrimitiveArray<T> rhs) where T: struct, INumber<T>` - `public static Array Take(Array array, IList<int> indices)` - `public static Int64Array CastInt64<T>(PrimitiveArray<T> array) where T: struct, INumber<T>` - `public static Int32Array CastInt32<T>(PrimitiveArray<T> array) where T : struct, INumber<T>` - `public static FloatArray CastFloat<T>(PrimitiveArray<T> array) where T : struct, INumber<T>` - `public static DoubleArray CastDouble<T>(PrimitiveArray<T> array) where T : struct, INumber<T>` I also have a generic visitor for converting `Large*` arrays to their regular counterparts so that they may work with the other machinery in the library. I am less confident that is useful to others, or that it is truly correct. Is there a particular pattern you would want these to follow or is the notion not suitable for the .NET ecosystem? I am less familiar with .NET as an ecosystem. Thank you. -- This is an automated message from the Apache Git Service.
