I wonder if it is possible to just keep s.ver == nil?

Definitely can do that, just would result in more LOC changed.

@sgtsquiggs, maybe we should keep the current approach. Is this PR ready for merge?

When will this happen? If it never happens, can we just delete it?

On the other hand, if the case does happen, we should not return nil either.

I modified the script (here) to return nil if the ver arg is not present. Alternatively I could have used another script that does not perform optimistic locking, and forked based on r.schema.verless.

Oh, can we align with the original behavior to return ARGV[2] as well?

Absolutely. Wrote this PR quickly so I could fork and use om - looking at this code today I don't remember a lot of it and it looks a little dodgy to me. I'll try to reimplement a bit cleaner this week.

Same here. Can we delete this?

Field names should be explicitly specified.
