It's used under the hood by my hs-opentelemetry suite, and managed to get some significant speedups. A full read-write cycle over values in thread-local-storage have been sped up from ~248 ns to ~13 ns on my machine. 19x faster!14 Apr 2026 13:22 +0000at://did:plc:55kp2u2cj32xojj2rokghg5v/app.bsky.feed.post/3mjhhyfdtic2fhttps://bsky.app/profile/iankduncan.com/post/3mj4stafedk2kThe U.S. consulate in Amsterdam is effectively closed due to the Iran war, and they haven't posted anything on their homepage about it.

Have to make breaking api changes this time, so it’ll be a big bang release of lots of things at once.
