Yes, it is of interest here. What I think is interesting here that he says that in practice the compiler could infer when to use move and borrow without using the new keywords "sink" and "lent" and they would gradually be removed. The same is pretty much analogous to letting the compiler analyze the code in order omit increasing/decreasing reference count which is he also mentions. This also what I think should be approach in D, which is borrow checker should stay out of the way as much as possible without any additions to language syntax.

The current O/B design in D has zero additions to the syntax other than an ` live` attribute for a function. It relies heavily on leveraging the existing DIP25 and DIP1000 implementations. I know it's been a hard sell for those two, but it's paying off.

Yeah, I'm following your live feature and it will be very interesting to compare the solutions once they matured.
