Assembly-level global using directives for the Editor assembly. Declares common namespaces (System, collections, IO, LINQ, Sandbox, Editor) as global so they are available across the assembly.
// What the game's editor assembly used to supply from elsewhere.

They are stated here rather than added to 22 files. global using System; global using System.Collections.Generic; global using System.IO; global using System.Linq; global using Sandbox; global using Editor;
