Comprehensive Error Handling & Validation System #71
Description
This enhancement would add:
Template Validation API - Validate templates before processing to catch errors early
Enhanced Error Messages - Show which variable/formula is missing, what type was expected, with line context
Error Recovery - Graceful fallbacks instead of crashing
Debug Mode - Detailed logging of template processing steps
This is valuable because:
- System-wide impact - affects all users of the library
- Improves DX - developers get clear error messages instead of cryptic failures
- Production ready - prevents silent failures in production
- Debugging - helps developers understand what went wrong
- Reusable - can be used across all template processing workflows
