- Cleaned up whitespace inconsistencies across multiple files.
- Removed the unused 'bit' module from the project.
- Updated comments and documentation for clarity.
- REFACTORED SINGLE-FILE COMPILER! Replaced with behaviourally identical modularised version.
- tested integrity of 'identical' using Vmify on seed 1 with NameGenerator set to Mangled.
- Removed unused dependencies initialised in pipeline.lua.
- Removed unused functions from util.lua previouslty used for compiler_old.
