function loadedFunc, Context ctx, Hook hook Sandbox:Load(string code, table env, bool mergeMode=false)This loads the supplied code as a function and sets the environment. This is the same as Context:Load with the exception that it creates a sandboxed environment if an environment is not provided. Generally you should provide a sandboxed environment (e.g. by extending an environment generated by the below function) if you provide one at all.
table environment, Hook hook Sandbox:MakeEnvironment(Context context)This returns a sandboxed environment and a Hook (see Hook API) for the supplied context.
