zeitwerk

Zeitwerk uses absolute file paths for require calls, eliminating costly filesystem lookups in $LOAD_PATH, as noted in the README's emphasis on performance.

Built for multi-threaded environments with coordinated reloading, ensuring safety in web applications, though it requires manual lock implementation.

Relies on predictable file-to-constant mappings, simplifying code organization without extensive setup, as highlighted in the philosophy section.

Supports coexisting loaders in the same process, each managing separate project trees, enabling modular dependency management.
