[Haskell-cafe] GHC Extension Proposal: ArgumentBlock

[David Kraeutmann]

It's not something that belongs in an extension. Rather, it should be
in the main language.

Let's say you want to write f (\x -> x) (\y -> y) and forget the parentheses.

How would you parse the following under ArgumentBlock:
f \x -> x \y -> y?
