I'm a big fan of declarative programs.
That said, declarativeness (especially in Python) is more a matter of
"notational flavor" than anything we can measure. It's certainly
independent of whether there are actual side-effects.
Also, I'm suspicious of any heroic efforts to prevent language
features from being "abused". Some of the most powerful techniques in
many languages were not envisioned by the language designers. The
languages I like (by their nature) tend to encourage the invention of
these unforseen techniques. Python is one of them.
