Hi,
PFA v2 of the patch fixing behavior described in
examples 2, 3, 5, 8, and 11 from the proposal paper.
I have also expanded the test cases to cover the
relevant behaviors described in the paper.
The ambiguous column behavior described in example 6
is not changed in this patch, but it can be easily updated
with a simple if condition if required.
Regards,
Hunaid Sohail
