sizeof: new package with constants for Int, Uint, Uintptr, Int8, Float64, etc
Read on GitHub See the tail of the (closed) proposal 5602. There I suggested that instead of making unsafe.Sizeof a safe thing, which it still kinda isn't in general
Issue #102
Rob Pike's sizeof package accepted for Go
Rob Pike's long-running proposal for a sizeof package, offering constants for the sizes of Int, Uint, Uintptr, Float64 and friends, has been accepted, closing out a thread that traces back to the old debate over making unsafe.Sizeof less unsafe. Elsewhere in the proposal queue there's a smaller quality-of-life pitch to have database/sql guarantee zero values on Null* types when Valid is false, which anyone who has written the same three-line unwrap helper for the tenth time will recognise. On the security side, advisories land for OpenFGA, Nezha and emp3r0r, all narrow enough that only their users need to pay attention.

Does anyone know of a public collection of sample binaries?
Read on Reddit I am looking for a collection of sample Go binaries, compiled with different versions of Go, for different platforms - It does not matter which files - a simple "hello world" program would do nicely.
