update_all isn''t as expressive as it should be

I would like to be able to do the following :

UPDATE table SET column1 = column2 + column3 -> for the whole table ,  and 
it is simply impossible with the current form of update_all !

I have to use simple update or ActiveRecord::Base.connection.execute to get 
the job done ... I think this should be a key feature for the future.

What''s wrong with Model.update_all(''column1 = column2 +
column3'') ?
This has been possible since forever :)
