True, this is one reason I did not take that syntax approach in Hg.
Not to mention other related abmiguity problems you have discussed in
the past on this topic...  (Another reason is I had no clue how to do
it another way!).  I was just wondering if there might be an easy way
to accommodate those who do desire that syntax (as several recent
posts indicate).

My thinking was, if just perhaps the last item could *always* refer to
a page name, and a / or . could be used without problems in PmWiki you
could have something closer to what is sought.  Of course, under the
surface it would still be Group.Name.  Just appearances.

I am sure PmWiki could be made to convert a url to Group-Group.Name
from whatever syntax was chosen, though that might require a core
change or two (how does cleanurls do it?).  Admittedly this would not
solve the underlying issue of pages being both a group and a name, and
it could therefore, lead to confusion for some.

(Specifically Animals/Canine/Dog would have the properties of
Animals/Canine and not the properties of Animals/Canine/Dog which is
what you might want if you saw it as the homepage for that group, ie,
it should look like Animals/Canine/Dog/Small and
Animals/Canine/Dog/Large...  But if that's the expectation, that two
could probably be worked out easily enough...  A fairly small step...
But then what do you do if you want a Dog page in Canine?  Using a
closing/ or . could indicate you add a HomePage to the end...  That
might do it...)

Personally, Hg accomplishes the goals I have at present, so I am happy
with it as is (I hide my ugly urls in a frame)--though I'm open to
improvements... On the other hand, I would be interested in seeing if
someone can suggest a problem Hg should be able to solve that this
recipe cannot (apart from notation).  That is we might get better
progress shifting our focus towards finding a way to extend its
functionality further as Kathryn is doing with hierarhical pagelists,
and I'm doing with ZAP's new subgroup stripping markup.  IOW, is there
anything anyone wants that Hg cannot do?
