Carl Steinbach commented on HIVE-1465:
--------------------------------------
I think that the current behavior of 'set' is actually correct. In my opinion
you want to be able to see the actual value of the property pre-evaluation,
though I do think it makes sense to add a switch to 'set' that allows you to
force property substitution.
