You mean 'get' method should not alter the dict, does 'dict[key]' should not
alter the dict either?
d = defaultdict(set)
assert len(d) == 0
print d[1]
assert len(d) == 1
auto insert value to dict, when value is not in dict, is what defaultdict
try to do.

Here is the next problem. For boolean/logical fields, I can set their
value to True/False easily. However, setting NULL seems impossible:
rec = tbl.newRecord()
rec["SOMEFIELD1"] = True # Works fine
rec["SOMEFIELD2"] = False # Works fine
rec["SOMEFIELD3"] = None # Will store False
rec["SOMEFIELD
