Here is a simpler version that doesn't use locals:

: when-drop ( obj question-quot: ( obj -- ? ) true-quot: ( obj -- ) -- )

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
