+--- This module provides encoding and decoding of Lua objects to and
+--- from JSON-encoded strings. Supports |vim.NIL| and |vim.empty_dict()|.
+
+--- Decodes (or "unpacks") the JSON-encoded {str} to a Lua object.
+---
+--- - Decodes JSON "null" as |vim.NIL| (controllable by {opts}, see below).
+--- - Decodes empty object as |vim.empty_dict()|.
+--- - Decodes empty array as `{}` (empty Lua table).
+---
+--- Example:
+---
+--- ```lua
+--- vim.print(vim.json.decode('{"bar":[],"foo":{},"zub":null}'))
+--- -- { bar = {}, foo = vim.empty_dict(), zub = vim.NIL }
+--- ```
+---
+---@param str string Stringified JSON data.
+---@param opts? table<string,any> Options table with keys:
+---                                 - luanil: (table) Table with keys:
+---                                   * object: (boolean) When true, converts `null` in JSON objects
+---                                                       to Lua `nil` instead of |vim.NIL|.
+---                                   * array: (boolean) When true, converts `null` in JSON arrays
+---                                                      to Lua `nil` instead of |vim.NIL|.
