I understand this, but I'm a bit confused about fate of lambdas with such guideline since I see no more reasons to use them with p.9 statement: long lines, code duplicate, no mock and well tests etc. - all these problems could be solved with assigning lambda to some name, but now they are looks useless (or useful only for very trivial cases)

I do not understand most of that, but... The guideline is not meant to cover passing a function by parameter name. mylist.sort(key=lambda x: x[0]) is still ok. Does "Always use a def statement instead of assigning a lambda expression to a name." need 'in an assignment statement' added?
