Plone: Reverse Folder Contents in TAL Define

Using TAL, I needed to display the folder contents with dates ascending (newest first). By default context/folderlistFolderContents returns the tuple descending.

So I fixed it by using a ternary statment hack, that evaluates both entries/blocks.

[code]
    <metal:fill fill-slot="main">
      <metal:main_macro define-macro="main"
            tal:define="portal_type python:here.getPortalTypeName().lower().replace(' ', '_');
            folder_list context/folderlistingFolderContents;

            folder_list python: (folder_list.reverse(), folder_list)[1];

            base_macros here/base/macros;
            view_template python:'%s_view' % portal_type;
