/** Interface to launch lua scripts using the [LuajClassLoader].
 * 
 * *Note: This class is experimental and subject to change in future versions.*
 * 
 * This interface is purposely genericized to defer class loading so that
 * luaj classes can come from the class loader.
 * 
 * The implementation should be acquired using [LuajClassLoader.NewLauncher]
 * or [LuajClassLoader.NewLauncher] which ensure that the classes are
 * loaded to give each Launcher instance a pristine set of Globals, including
 * the shared metatables.
