Saving the indentation? Oh yes, for sure! This code reads like a story, the indentation is superfluous to that story. Should we add it to Python? I don't know; I quick scan through my own code, and I do not see much opportunity for list comprehensions of this complexity. Either my data structures are not that complicated, or I have try/except blocks inside a loop, or I am using a real query language (like SQL). pythonql seems to solve all these problems well enough (https://github.com/pythonql/pythonql).
