Packed Data Support in Haskell

- Packed data allows using data as-is without deserialization, improving performance by leveraging L1 cache.
- The packed-data Haskell library enables packing, unpacking, and traversing data without marshalling steps, using Template Haskell.
- Key features include Packable and Unpackable typeclasses, NeedsBuilder for buffer management, and PackedReader for type-safe reading operations.
- Benchmarks show mixed results: some operations are faster (e.g., AST evaluation), while others are slower (e.g., right-most node retrieval) compared to native Haskell.
- Future work includes optimizing PackedReader by generating C code via AST to reduce overhead and exploring similar approaches in other strongly-typed languages.
