How about:
f x y . g x $ z
then you only need to add the line
. h x y
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...
