●●SolidBig BrainNiche Gem
Backdating equal results keeps downstream consumers valid without re-running.
Strengths
- •Strict mode freezes returned values to prevent accidental mutation bugs.
- •UntrackedReadError blocks raw open() calls to enforce dependency tracking.
- •Zero runtime dependencies and stdlib-only makes deployment trivial.
Weaknesses
- •Pure Python implementation may struggle with performance compared to Rust alternatives.
- •Niche audience limits adoption to specific reactive programming use cases.
