The tarball for SMW 1.3 had the script SMW_Template_Declare.php in its 
includes/ directory. But a quick scan of Special:Version shows that 
neither "declare" nor the other experimental keyword, "set," are active 
in 1.3. Will these be active in 1.4? For that matter, how might I 
activate them (especially "declare") now, other than subscribing to SVN? 
That is, what files contain the lines for making "declare" an active 
parser hook?

I still have my "historical date" data type (SMW_DV_HxDate.php). The 
thing that I desire most in a "date" data type is a range that 
encompasses the whole of recorded history. That's why I wrote 
SMW_DV_HxDate.php (which is so large by now that I can no longer send it 
as an e-mail attachment). I'd be interested in learning (or reviewing) 
what features others might desire in a date (did someone mention support 
for time of day?), so that I can try to build those in.

Finally, I would like to see support for doing /arithmetic/ with 
numerical properties. Right now one can compare property values, of 
course. But I might like to run a query that applies common statistical 
functions to multiple articles--sums, means, medians, modes, standard 
deviations, ranges,...
