Question still stands if this type of code needs compaction in the first 
place?

List comprehensions usually have some sort of declarative touch (set 
builder notation).

Even though, striving for a more compacted version, I tend to think that 
using a declarative version of it doesn't serve it well in the long term.


We recently came across the following code snippet in our source base 
(1st answer of 
https://stackoverflow.com/questions/480214/how-do-you-remove-duplicates-from-a-list-whilst-preserving-order). 
It was absolutely not comprehensible.


Your example is inherently imperative because the internal state changes 
from iteration to iteration; something unusual for set builder notation.
