What's the status of atomicity of file-copying and -moving (renaming) using std.file on different platforms?
For renaming that's a good question, but for copying, no-one should make atomicity guarantees. It's inherently non-atomic, and if you try to build an atomic wrapper around it (by trying to catch failure cases and deleting the file), you'd be ignoring cases like power failure, system hang, process crash. Some of those could be achieved on some OSes, but I doubt all of them can on all OSes.
