alt Hacker NewsTemplate Haskell is actually pretty cool. Using it to generate lenses in a type is a perfectly fine use case (of course hand-writing lenses is just one line anyways). Running computation at compile time is really a great feature; people rave about comptime in Zig but of course Haskell has had it earlier.
I don't dispute the coolness of any given Haskell feature. Haskell does have a lot of really neat features, but that doesn't mean that the language is fun to use.
C++ also has a lot of really cool features but I also do not enjoy writing it, actually for similar reasons as Haskell (though I don't think Haskell is nearly as irritating as C++).

The lenses themselves aren't hard to write; I was referring to the annoying quirk of Haskell where records couldn't have the same field names. Lens has a nice helper macro `makeFields` so that you could more or less automatically have the generated lenses have the clashing names.
To be fair it actually always worked fine for me but it always felt janky until `DuplicateRecordFields` was released.
