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!
