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.
This is the style I am using for records and lists as well. Here an
example from actual code
data EventNetwork = EventNetwork
{ actuate :: IO ()
, pause :: IO ()
}
These days, all my record definitions look like that.
Allowing a superfluous leading comma would be great, because that makes
it easier to move around the first line.
