When you're writing Haskell in emacs (like you should be), you enable haskell-font-lock-symbols in haskell-mode, and it displays the lambda as it should be (plus a bunch of other symbol corrections for ::, ->, =>, (), ||, &&, etc.)

Mmm I suppose it's really just preference. I love that syntax. But I guess there's no arguing about taste.

Well, it's typing-friendly but not (re)learning-friendly. I guess it depends how you weigh those concerns.

It's also very reading friendly.

I normally forgive languages being hard to learn if the bring enough utility.
