set function is a combination of JP's set or delete functionality with k/q's upsert, with "merge" oriented optimizations for bulk oriented upserts. To get JP's upsert or delete functionality, whenever value is null, delete is performed. This corresponds to keyhasnullvalue get kvdata returns the same when k is not found or associated value is null, and so (key;a:) set kvdata provides the same results if key is deleted as if it were associated with null.
