How about:
f x y

then you only need to add the line

But then you have a problem when you when you want to add something
at the beginning ;-) With right-assoc $ adding at both ends is OK.
This is similar to how people often format lists:
a =
[ first
, second
, third
]
I am one of those people, and I am slightly annoyed with I have to
add something at the beginning of the list. I even went so far that
when I had a list of lists, which were concatenated, I've put an
empty list at front:
concat $
[ []
, [...]
, [...]
.
.
.
]
Just in case you are interested, in the "preprocessor" I'm writing, I would
write these examples as:
(.) #>
f x y
g x
h x y
$ z
and
a = #[
first
second
third
where exp #> {e0,e1,...} is sugar for let a = exp in a e0 (a e1 (a ... )
...)) and #[ {e0, e1, ... } is sugar for [e0, e1, ...] (exp #>
block and exp #< block are the right and left associative versions
respectively and the special # sugar allows a layout block to be started if
it occurs at the end of a line)
This allows me to avoid having to type lots of syntax eg repeating the "."
all the time and focus on the semantics...
