I think it should only have an UnsafeRawBufferPointer version. If the user wants to bind memory, they should do that explicitly. I’ve made the likely changes to Data on a branch:
There are enough changes to Data that I think it deserves a separate proposal and discussion thread. It’s useful to look ahead at how the Data API should look but I’m trying to get language-level changes accepted first (in some sense, Unsafe constructs are part of the language even if they don’t require compiler changes).
Also keep in mind, adding UnsafeRawBufferPointer does not make Data any less usable today. We just need to get core support in place so we can have a discussion about Foundation.
