I'd suggest transplant is actually move - an idea which has been taken to the level of obsession in modern c++ and new languages like Rust (which I want to like - but it's highly technical demands just leave a bitter taste in my mouth - impressive, yes; the right approach - definitely not, IMHO anyway!).
For LCS 'move' would allow to elide a put and delete. However there are few cases I can think of (if any!) where it is required save for the fact it would make certain things potentially more performant in the absence of even a relatively simple data-flow based optimisation phase. Also I'm not sure it could be implemented in the current LCS mechanism to actually give that performance so it would essentially be a bit of syntactic sugar for 'put' then 'delete'. Perhaps reasonable from the point of view of clear expression of intent though! Warmest Regards, Mark.
