I often wish for a map vmethod, too.  What I might do in perl (for,
say a breadcrumb ):

    join '&#187;', map {
        $_->here ? $_->text : qq[<a href="$_->url">$_->text</a>] 
    } @links;

(escaping where needed)  and in the Template I do:

[%- 
    mylist = [];
    FOR item = page.trail;
        SET escaped = item.name | html;
        SET tooltip = " title=\"$item.tooltip\"" IF item.tooltip;

        IF item.here;
            mylist.push( escaped  );
        ELSE;
           mylist.push( "<a href=\"$item.url\" $tooltip>$escaped</a>" );
        END;
    END;
    mylist.join(' &#187; ');
%]

I suppose the second is easier to read.
