That is not a real drawback, as "sys" will certainly be present in the 
system, so the "importing" boils down to a dict lookup and a variable 

Having said that, I'd add that I found the behavior of __import__ 
counter-intuitive, but assumed there's a good reason for it.  If I 
hadn't known about sys.modules beforehand, I would have probably gone 
the chained-getattr route as well.
