Hi Markus --

I'd been vaguely thinking of doing this a while ago, but never got around
to it.  WebMake has separate sets of tags for the .wmk file, and for
inside content items -- and <for> is only defined in the former set of
tags.

However, defining a plugin to do it, using the "define_tag()" API would
be *very* easy, and I'd be happy to include it in the distribution ;)

I would suggest using a different name for the tag instead of <for>, just
to avoid confusion with the .wmk-file tag <for>.  <multiple> is used by
the ACS Templating System [1] -- or <foreach>, or whatever...

PS: but in the short term you may be happier with this:

        <content name=repeated_item>......</content>
        <content name="main">
            <{perlout
              foreach my $x (1, 2, 3) {
                print get_content ("content_$x");
              }
            }>
        </content>
