With full respect to haiyang kang, hear-say from one person can hardly 
be described as "strong" evidence -- particularly, as Alexander 
Belopolsky pointed out, the use-case described isn't currently supported 
by Python. Given that what haiyang kang describes *can't* be done, the 
fact that people don't do it is hardly surprising -- nor is it a good 
reason for taking away functionality that does exist.
