Description

Just stumbled over this on trunk:

cqlsh:test1> select a, b, c from table1;

a | b | c
----------
1 | b | 2
2 | null | 2.2

(2 rows)
cqlsh:test1> select a, a, b, c from table1;

a | a | b | c
---------+-----
1 | b | 2 | null
2 | null | 2.2 | null

(2 rows)
cqlsh:test1> select a, a, a, b, c from table1;

a | a | a | b | c
----------------------------
1 | b | 2.0 | null | null
2 | null | 2.20000004768 | null | null

My guess is that his is on the Python side, but haven't really looked into it.
