OK, you asked for it <wink>:
/>> def beargh(d):
|.. unique = []
|.. def ouch(x,y):
|.. if x is unique:
|.. return y
|.. else:
|.. d[x] = y
|.. return unique
|.. return ouch
\__
->> d = {}
->> reduce(beargh(d), ['a', 1, 'b', 2])
[]
->> d
{'a': 1, 'b': 2}
you may have underestimated what I meant by horrible :-)
Cheers,

Counting lines is probably a good idea if you want to print it out
and are short on paper, but I fail to see the purpose otherwise.
