    % Unfortunately, this causes a nasty bug with MATLAB: calling this

    % normally forbidden. The consequences of that are nasty: adding a
    % class to the dynamic class path can be refused, because it would be
    % falsy recorded in the static path. On top of that, the static
    % path is fsck in a weird way, with file separator from Unix, causing a
    % mess on Windows platform.
    % So we give it up as now.
