Sorry, but I disagree on this one:
1. this is a test - it should be readable code before complex code
2. if there will be exception on this line with multiple methods, it is going to be more difficult to debug
3. returned_user1 is only a reference of the object it uses very very little memory
4. I think this is more of the personal preference, than actual issue
if I am wrong on any of the 4 points, please do tell.
