Comprehension are very much based on the idea of *declarative* data
collections. That's their entire reason for being. In general, one
expects comprehension to be side-effect free and just build a collection
according to declared rules. Obviously I know many ways to smuggle in
side effects, but doing so goes against their spirit and user expectations.
A comprehension should read as one line. At very least logically, but
usually physically. If I ever find myself wiring a comprehension longer
than about 120 characters, I know it's time to refactor into a function
and block loops. I've cleaned up far too much code that used too-complex
nested comprehension.
Everything about this proposal is antithetical to the intention of
comprehension.
I concur with David.
