An alternative frontend for Haskell?

[jackdk]

I don’t think |> and <| are good ideas for Haskell, because you cut yourself off from a lot of historical code, as well as from a consistent visual language which has grown up around those operators.

Informal discussion about the progression of `base`

Perhaps, but if we’d picked |> for &, we probably would never have invented the coherent operator language that we have now. We have (<$>) = fmap acting sort of like the “functorised” version of $, and if you know that (&) = flip ($), then you can guess what (<&>) will do. The mapMaybe operators from package witherable are similarly easy to predict: <$?> and <&?>. Having |> and <| would also cause a mnemonic clash with the “one-winged” operators like (<$), ($>), (<*) and (*>). I also think that …
