The ConditionalExtensions recipe provides some 
relational operators that might work -- see
http://www.pmwiki.org/wiki/Cookbook/ConditionalExtensions .

However, I'm also wondering if we should make the count= parameter in
(:pagelist:) use a syntax similar to the lines= parameter in
(:include:).  In other words:

    (:pagelist count=10 :)       # first ten pages
    (:pagelist count=1..10 :)    # first ten pages
    (:pagelist count=11..20 :)   # second ten pages
    (:pagelist count=11.. :)     # skip first ten pages

Previous proposals had looked at providing a "skip=" or "first="
parameter to pagelist, but this seems a bit more consistent.

e may still provide a skip= or first= parameter that can be
combined with count.  However, much of what skip= or first= would
do could be handled within the pagelist template itself, if 
some form of relational ops are available.

I'm still not certain of how to do paged output when the
pagelist template itself does some form of selecting records
to display.  Perhaps an (:if count:) directive or a {$Counter}
page variable that keeps track of the number of times it has been
evaluated in the context of a particular set of markup.  Or
perhaps a directive that increments a named counter of some sort.
