[hcaloto]

System (please complete the following information):

• OS: linux
• GO Version: 1.19
• Pkg Version: v1.4.5

Improvement:

It would be useful to have the original value in the final error message. In my use case I'm comparing a lot of rules at the same time and, sometimes, is not easy to see the original value that caused the error.

Example:

This is an approach to tackle it, for sure there are other better ways to do it, for example by using an error template.
