        #
        # The default generator for Haml::Engine is configurable via an engine option, like so:
        #
        # use :Generator, -> { options[:generator] }
        #
        # Because this Temple filter is set as a proc, the resulting effect within Temple's EngineDSL
        # is that the generator's valid options are not merged into the full set of options available
        # on Haml::Engine itself. This means we receive a "Option :capture_generator is invalid"
        # warning when we set our `capture_generator:` below.
        #
        # However, this option is perfectly valid, so here we merge all the options for Haml's default
        # generator into the top-level engine's options, avoiding the warning.
