Indeed ;) 

Basically an expression with embedded assignments appears as "untidy" as a 
loop with breaks. I read PEP 572, and the only convincing examples are those 
from copy.py and sysconfig.py where a sequence of tests that required nested 
if-s and can be flattened into if...elif...elif...

Over the years there were some really cool additions to Python (generators, 
list comprehensions, context managers), but for some time my impression is 
that the language is going from lean and mean to baroque.
