As Chris said, side effects in asserts are nothing new and this PEP is not the one to do something about it. Serhiy, have you even read the latest version of PEP 572? In its current form it does not introduce any implicit scopes and even goes out of its way to make assignments in comprehensions "leak" out of the comprehension scope into the surrounding (explicit, using 'def' or 'lambda') function's scope. -- --Guido van Rossum (python.org/~guido)
