I've been looking at the date range syntax in pagelists a bit
lately.  I'm thinking it might be too difficult to get it to
work using a simple $Var=<start>..<end> syntax, because there 
are too many conflicts with other things we might want to
match.

However, I'm looking at the following possibilities:

 - pages with names between 15 Mar 2007 and 07 Apr 2007

     dates=2007-03-15..2007-04-07

 - pages where $:Date is between 15 Mar 2007 and 07 Apr 2007:

     dates=$:Date,2007-03-15..2007-04-07

Or, as a somewhat different syntax that stays closer to the $Var=...
format, maybe we want something like:

    $:Date=date(2007-03-15..2007-04-07)

This of course means we cannot search for variables containing
"date(" directly without having some sort of pattern or special
marker in place, but I don't know that that's a big problem.
It also means we could have other functional comparisons:

    $:XYZ=gt(14)    all pages where $:XYZ is greater than 14

Or, following along the {(...)} syntax I proposed in another
thread for doing special functions, we might want

    $:Date="(date 2007-03-15..2007-04-07)"

or maybe 

    $:Date=(date 2007-03-15..2007-04-07)

Comments?

P.S.:  I'll answer the {$$var} issue in another thread.
