> …you have to remember Haskell's list comprehension syntax…

I get the point you're trying to make, but this feels like a huge stretch. Haskell's list comprehension syntax is straightforward and in many cases a terse and useful way of implementing complex functionality. You'll find multiple uses of it in the base libraries; notably, catMaybes is implemented in terms of list comprehension:

    catMaybes :: [Maybe a] -> [a]
    catMaybes ls = [x | Just x <- ls]

I'm all for reducing cognitive load, but Haskell has such a sparse syntax and this specific feature is so useful (and honestly, so consistent with the rest of Haskell's syntax) that arguing it's some kind of unnecessary cognitive burden feels ridiculous to me.

Yeah I mostly agree but I mentioned it because I spent some time trying to figure how how the leftPadding variable in the let block can be referenced outside the let block. It's been a couple of years since I've used Haskell.
