    # This works for now, but it's a kind of crappy solution because
    # BindableBlock adds and removes methods for each time it is invoked.
    #
    # A better solution would be to instantiate it before passing it to
    # the options, then we only have to bind it to an instance and invoke
    BindableBlock.new(instance.class, &default_proc)
                 .bind(instance)
                 .call(*invocation.args, &invocation.block)
