If just you're trying to avoid getting a repetitive strain injury in your
right-hand little finger from typing all the [''], you could turn
the keys into object attributes, e.g.:

	class DictObject:
	    def __init__(self, d):
	        for key, value in d.iteritems():
	            setattr(self, key, value)
	...
	o = DictObject(D)
	# use o.a, o.b, etc
