Researchers announce 'Pure Borrow', a system combining Linear Haskell's uniqueness types with Rust-style borrowing semantics, enabling safe mutation and concurrency in pure functional code. The work has been accepted at PLDI 2026 and provides type-safe, leak-free memory management with features like multiple aliasing and lifetime regions. This represents a significant advancement in bridging functional programming purity with low-level control.
Background
Linear Haskell extends standard Haskell with linear types (a %1 -> b) that enforce exactly one use of resources, enabling pure functional programming with fine-grained resource control. Rust's borrowing system provides memory safety through ownership and borrowing rules at compile time.
