 old-style redirects in the alias list, but that might introduce unwanted
 coupling with the meta directive.
 

+-----------------
+
+On second thought, implementing this might have similarities with
+[[todo/auto-create tag pages according to a template]] -- the auto-created
+pages would, if the way of the alias directive is followed, not create physical
+files, though, but be created just when someone edits them.
+
+If multiple plugins do such a trick, they would have to fight over who comes
+first. If, for example, we have a setup where not yet created tag pages are
+automatically generated as "\[[!inline  pages="link(<TMPL_VAR TAG>)"
+archive="yes"]]" and aliases are enabled, and a non-tag pages grabs a tag as an
+alias (as to redirect all taglinks of the tag to itself), there are two
+possibilities:
+
+* The autotag plugin comes first:
+    * autotag sees the missing tag and creates its "\[[!inline" stuff
+    * alias sees that there is already content and adds its prefix
+* The alias plugin comes first (this is the prefered way):
+    * alias sees the empty page, sees it is not contested by other alias
+      directives and creates its "\[[!meta" redirect
+    * autotag sees there is already content and doesn't do anything
+
+That issue could be handled with "priority number" on the hook, with plugins
+with a lower number being called first.
