Sorry...I somehow missed the key *uppercase* bit of that, and

Well, if you must, if you've just got the results in my
previous post, you can take them and shove them back into a
dict with
results = [('key1','value1'),('key2','value2)]
newDict = dict(results)
If you're not doing anything
well.
However, the core data summarisation/subsetting engine is thought to be
sound (and there are some unit tests to attest to that).
Probably not quite what you were after but I thought it worth a mention.
