This is for Lowerdash unfortunately. We have negligible access to the interpreter since pointers are so aggressively type-errored.
Lowerdash no longer uses PRGINS and the linear search it took to delete. Deletes now are just O(1). (linear wrt number of instance members and the memory use might be up...)
It might be more of a hint if I posted a screenshot with fragmentation.
