NAME_AND_LOG

Description

NAME_AND_LOG evaluates an expression, logs its result under a given name for debugging purposes, and then returns the result unchanged. It is a transparent wrapper — the rule behaves identically with or without it.

This is useful when troubleshooting complex rules, as logged values can be inspected without changing the rule's output.

Example

p is Person
NAME_AND_LOG('age_check', YEARS_AGO(p.date_of_birth) >= 18)

This evaluates the age check, logs the result under the key age_check, and returns true or false as normal.
