http://www.haskell.org/haskellwiki/Accessible_layout_proposal
I see two main problems with such a proposal (other than the particular details of the syntax chosen for it): - layout is not very well supported by most of the text editors, contrary to parens/brackets/braces. - more importantly: it introduces a new syntax that doesn't replace the old one, so it makes the language more complex. Compare that with the layout for `do', `let', `where' and `case' which is fine because it's used 99% of the time and the alternative syntax is the same for each one of them (simply add {;;;}). So I'd be OK with a switch from data foo = Toto | Tata Int | Titi to data foo = { Toto ; Tata Int ; Titi } and data foo = Toto Tata Int Titi and similarly for module import lists, but only if it comes with a deprecation of the current syntax.
