Dictionaries are 'dict' data types, that means
key=value set of pairs
so is easy to know always the name of a var and the value of the var... If I
understand correctly this dictionary is "exploted" to the view... I mean
it's key value pairs are populated to the view for access them directly,
some like
put in a controller:
def some():
return dict(key1="2343", 23=12)
def some2 dict("hi"="there")
now in your view:
{{=dir()]}
I guess it goes trough the manipulation over the elements of the returned
dict with some of http://docs.python.org/library/functions.html#locals or
http://docs.python.org/library/functions.html#globals
See here for furter understanding
