Yes, it will definitely be done, but not in the upcoming release. I'm pleased that people are asking about it; in general Ian and I are not sure what features are most desired. > > > One more thing, do I still have use remove-kv with drop-pobject? > > yes. if you'll just do drop-pobject but not remove-kv, you'll be able to > retrieve object from btree, but reading slot will cause slot-unbound error, > that way you'll know object isn't there :) > at least this way documentation suggests, i didn't try it myself: I don't understand why you would explicitly call remove-kv. Without a code example, I can't be sure precisely what is intended, but remove-kv is a low-level API call for cursors and btrees directly. If you are using Ian's Persistent classes, I seriously doubt you would want to call it directly --- and if you do have to for some reason, it is an oversight on our part. > > drop-pobject reclaims persistent object storage by unbinding > all persistent slot values.
