Function name `scatter` conflics

The function name `scatter` in DistributedArrays conflicts with the `scatter` function in, say, 80% of all julia's plotting packages (for making scatter plots). Would it be possible to rename to something unambiguous, such as `distribute`?

Start by locating the DistributedArrays `scatter` definition and its callers, then review how the public API exposes that name. Determine the affected usage and compatibility surface for an unambiguous replacement, and verify that the renamed entry point and relevant package behavior remain covered by the existing tests.
