Allocating on the Stack in Go 1.25+ — Go 1.25 and 1.26 reduce garbage collector overhead by stack-allocating slices in more cases than ever before — including, in 1.26, slices that eventually escape to the heap. "The optimization that Go 1.26 does is actually better than the hand-optimized code" is always good to read. Let Keith explain how this all… stacks up.
