Correct.  Anything that has the yyyy-mm-dd format
somewhere in the string (or the other formats I listed) 
can be parsed as a date.

Dates could come from a lot of places -- page names, page variables,
page text variables, input forms, etc.  So, this gives us a way
to work with them all.

Page names cannot contain a '@', but I suspect it's not common
to have a Unix timestamp in the middle of a pagename.  For page names
that are themselves unix timestamps, one can always do something like
the following to include the leading '@':

    (:if date 2007-05-01..2007-05-31 @{*$Name} :)

If we need anything more than that, there are a bunch of ways
for us to be able to get there.  :-)
