The [function-references](https://github.com/webassembly/function-references) proposal introduces a `let` construct that provides the ability to implement `dup`. In essence, it allows you to create new locals from stack values. Some have also suggested...

Similarly, many of the atomic operations could have been expressed by using an `atomic` prefix. However, the branch hint prefix feels like a slightly different case, since it behaves as...
