There's a weird idiom that I see all the time in Haskell code where coders put commas at the beginning of lines:
data Thing = Thing { x :: Int ,y :: Int ,z :: Int ,foo :: String } ...
items = [ "red" ,"blue" ,"green" ]
(I don't think this is valid Haskell. The closing } and ] should be more indented). I like to put commas at the beginning of lines, because there, I can make them line up and it is visually clear that they are all at the same nesting level. I like how the commas look a bit like bullet points. For example, I would write: items = [ "red" , "blue" , "green" ] Could we extend Garett's proposal to also allow prefixing the first element of a list with a comma, to support this style: items = [ , "red" , "blue" , "green" ] Allowing an optional extra comma both at the beginning and at the end would allow programmers the choice where they want to put their commas.
