Comment on Lens: Lenses, Folds and Traversalsparent

But there's nothing 'verboten' about this in Haskell! Haskell could allow for the exact same syntax, and do the exact same thing behind the scenes. Oh but no, LENSES of course, you must rewrite obvious code in the most obtuse manner possible. :)

Unlike JavaScript, it would require fundamental changes to the language itself, so I don’t think it’s really a fair comparison.

But lenses already do the same thing, just with a worse syntax. do notation already rewrites a lot of messy Haskell into cleaner Haskell. It's not that different!
