I still believe Python comprehensions have confusing structure and in real code I've seen it's 10x worse with 5+ expressions packed in a single line. I much prefer a Nim's style of list comprehensions:

    let a = collect:
      for word in wordList:
        if word notin bannedWords:
          word
    let b = collect(for x in list: x)

It's still very terse, but, more importanly, it's the same syntax as a regular `for loop`. It has the structure, where in Python complex comprehensions look like a "keyword soup".
