Top 3 Haskell Modular Projects

  1. streamly

    High performance, streaming and concurrent functional programming in Haskell

    It's hard to point to what's idiomatic given such low level fp primitives.

    Something like https://github.com/composewell/streamly can go very fast and constant memory with 0 allocs.

    Once linear types get better support, it would be nice.

    Both Rust and Haskell are fairly high-level and I'd bet with proper primitives in both languages it is impossible to reason about register use or performance.
