They dates from < 2027 and are quite outdated. Favour the nl
translation instead.
n_BE is not on Transifex so it was not possible to correct bad
translations.

Use the `fragment_to_query_string` decorator before the `route`
decorator on a controller endpoint. Traceback when the endpoint is
called as a `str` object is not a `Response` object.

Since httpocalypse it is advised that all decorators used with http-type
controllers return a Response. This makes it possible to decorate the
endpoint in any order, even before `@route`.

    # Preferred
    @route(...)
    @fragment_to_query_string
    def endpoint(...):
        ...

    # This work
    @fragment_to_query_string
    @route(...)
    def endpoint(...):
        ...
