Proposal floats container/hash.Set with custom hash and equality

Alan Donovan has filed a proposal for container/hash.Set, a hash.Set counterpart to the earlier Map work that lets a set key off the element type's own hash and equivalence functions rather than Go's built-in comparability. Alongside it, a Reddit thread asking which standard library package deserves more attention is drawing the usual affectionate arguments, which pairs neatly with a proposal aimed at filling one of the stdlib's longer-standing gaps. On the security side, a handful of Gitea advisories and an out-of-bounds read in klauspost/compress/s2 are worth a scan if either shows up in your dependency graph.
