This work also led us to reexamine finalizers, resulting in another proposal for an easier-to-use and more efficient replacement for finalizers. With a hash function for comparable values on the way as well, the future of building memory-efficient caches in Go is bright!
It is wonderful to see that the Go team is working on improving the memory management of Go.
Inline Heuristics Review
On Thursday 3/28 we held a design review looking at the new inlining heuristics framework being developed as part of the inlining overhaul effort (this was a separate session from the usual C&R meeting)
