Two changes of note since the discussion started: * The option to mix explicit capture and implicit capture has been removed as too confusing/unpredictable. Either trust the engine to capture the right things (the new syntax proposed here) or explicitly list everything (the existing syntax we've had since 5.3.) * We added a section discussing the use(*) syntax alternative, and why it wasn't, er, used.
