Recently I came up with a related idea for repeated error handling code, in the usual Python vein of introducing an abstraction to save 2-3 lines:

    try:
        foobar
    delegate handle_stuff:
    delegate handler_factory(something):
    except Foo:
        ...
    else:
        ...
    finally
        ...

Where "delegate handle_stuff" means that for any exception handle_stuff is called with the exception tuple and the exception is considered handled if it returns truthy. "delegate" of course takes an expression so that you can have Proper Adult Fun Handling Exceptions.
