 * _Interfaces_ and _generics_ provide first-class alternative to hacky preprocessor-based or string-pasting shader specialization. Preprocessor hacks can be replaced with a well-understood language feature already used in Rust, Swift, C#, Java, and more.
 
+* _Automatic differentiation_ greatly simplifies the implementation of learning-based techniques in shaders. Slang supports automatically generating both forward derivative and backward derivative propagation functions from forward computation code.
+
 * Slang supports a first class _module_ system, which enables true separate compilation and semantic checking of shader code. 
 
 * Slang supports compute, rasterization, and ray-tracing shaders

 As you can see, `hello-world.slang` is no different from a normal HLSL shader file. In fact, Slang is compatible with most HLSL code you would write. On top of HLSL, Slang has added many new language and compiler features that simplifies various tasks with shader code, which we will cover in future chapters. For now we will demonstrate one key feature of Slang: cross-compiling to different platforms.
