●●SolidBig BrainWizardry
Frozen values and tracked reads prevent mutable state from breaking memoization.
Strengths
- •Strict mode raises TypeError on mutation, catching cache-invalidating bugs early.
- •UntrackedReadError enforcement prevents accidental dependency on external state.
- •Backdating support enables early cutoff for comment-only file edits.
Weaknesses
- •Zero stars indicates unproven stability for production incremental computation workloads.
- •Incremental computation is niche—most Python developers don't need Salsa-style engines.
