 ## Errata
  * 2023-08-08 -- After this CHIP was finalized, the definitions of CHIP Sub-categories were modified. Please note that while this CHIP is sub-categorized as `Chialisp`, under the modern definitions it would be sub-categorized as `Primitive`.
+ * 2025-09-29 -- This CHIP's sub-category was originally listed as `Chialisp`. That category is meant for changes to the language itself. To correct this mistake, the new sub-category for this CHIP will be `Primitive`.
