These layouts feel a bit artificial to me. I am quite partial to python's list syntax - a trailing comma is optional. meaning you can write
[ a, b, c, ]
I'm surprised this approach isn't more widespread - Are there reasons why haskell syntax could not/should not be defined this way?
I think this would be confusing because it looks like a syntax error - the last element is missing. The advantage of just having comma as a separator is that it allows syntax errors to be detected, whereas making it optional would mean one less error is detected at compile time. I'll take this opportunity to re-present my hyper-cool syntax proposal for lists ;-) : #[ a b c No need for commas or a closing ] because we could just use layout!
