description	Apply modern Go guidelines for go-revjs, targeting Go 1.23 features that are valid for this repository.

Modern Go For revjs

This repository targets Go 1.23.0 and uses toolchain go1.24.2.

When writing Go code here, prefer modern standard-library patterns that are valid for Go 1.23 without relying on newer language or library features.

Prefer

• any instead of interface{}
• errors.Is and errors.As for wrapped error checks
• errors.Join when multiple independent errors need to be returned together
• strings.Cut, strings.CutPrefix, strings.CutSuffix over manual slicing when appropriate
• slices and maps helpers instead of manual loops when that makes the code clearer
• min, max, and clear where they simplify logic
• sync.OnceFunc and sync.OnceValue for one-time initialization helpers
• time.Since and time.Until instead of manual subtraction

Avoid

• Patterns that require Go 1.24+ language or library behavior in production code
• Legacy helper code when the standard library already provides a clearer option
• Overusing new helpers when a plain loop is still easier to read

Practical Rule

Use the most modern approach that keeps the code obvious to maintainers already working in this codebase.
