[Zope] Core Session Tracking Usage Question

[Aseem Mohanty]

Ho do I totally clear a session variable or an entire set f session 
variables when using Core Session Tracking.

if data = session_data_mgr.getSessionData()
Setting every variable to _.None by data.set('...',_.None) is too 
cumbersome and I just found that data.clear() does not work.
So how do I do it ie clear one or a number of session variables??

TIA
AM
