The current way is:

if sessiondatamanager.getSessionData()['mykey'] == 1:
    .. do something...

I suppose you'd rather see:

if sessiondatamanager.getSessionData().mykey == 1:
    .. do something...

Is this really worth it?

And this is currently:

sessiondatamanager.getSessionData().set('b',1)

You can't do assignment in DTML, and session-tracking needs to be usable
from DTML, so the "ob.attr = val" idiom is out from the get-go.  Another
assumption I'm making is that  "there should only be one way to do it".  I'd
rather not have both __setattr__ and .set work for session data objects,
because it's confusing and doesn't buy anything at all other than a couple
keystrokes.
