For the Go programming language there has been discussion of adding a secret.Do function, that invokes a function closure and, after it returns, erases all memory that it allocated. The goal is better, though not perfect, forward secrecy, so that people can't capture a key today and a conversation today and, if they key becomes vulnerable, later use it to decrypt the conversation. There is a lot of discussion at <https://go.dev/issue/21865> with the output at <https://github.com/golang/go/issues/21865#issuecomment-925310304>. This is not yet implemented, but the current attempts require work in both the compiler and the runtime library. Related to that is a more speculative idea to enable ARM DIT/Intel DOIT mode while executing a function. Discussion at <https://go.dev/issue/66450>. But there is no special work in the Go compilers to ensure that code written to execute in constant-time is not optimized to run in non-constant-time. It would be interesting to hear about other work in that area. Ian
