It looks like constant construct expression (Array, Object). Which evaluate and store in value.
Later we return.
Problem with this is prepare (but can happen correlated subquries too)
At the end of execution, it might recycled (not sure where) and giving array of nil values, second execution of prepare statement.

If call here with.Expression().ResetValue() it re-evalaute constants. Or some how track if it is constant.
