[Zope] SQL Session docs need an update (at least for 2.1b2)

For those of you trying out 2.1beta2, and considering SQLSession, I have a rather import note. Problem: The docs say to use <dtml-var "SESSION.set('foo','bar')"> to set a new variable in the session. Apparently, the new dtml-var changes will print "None" at this point in your html. Can be damned annoying. Fix: use <dtml-call "SESSION.set('foo','bar')"> and None goes away. arghh .. must get sleep ... -- "They laughed at Columbus, they laughed at Fulton, they laughed at the Wright brothers.
