The only risk here is if your refactoring does something silly, such as
reusing a variable which overrides assignment:
How would you propose to write this code without reusing a variable?
stuff = 
for datum in data:
f = process_the(data)
g = munge_result(f)
Under the proposal, we have no guarantee that each iteration through the loop will give us a new `f` to work with. Maybe yes, maybe no. Without looking at the source code in `process_the()` we have no way of knowing whether `f` is being bound to a new object each time or some completely different arbitrary action.
Keeping medicines from the bloodstreams of the sick; food
from the bellies of the hungry; books from the hands of the
uneducated; technology from the underdeveloped; and putting
advocates of freedom in prisons. Intellectual property is
to the 21st century what the slave trade was to the 16th.
