IIUC, if the OP's proposal were accepted, the __del__ method would be 
called as soon as the *value*'s reference count went to zero. That means 
this wouldn't leave 10,000 files open, since each open() would assign a 
new file object to f, which would make the previous file object's ref 
count be zero, and it would be closed.
