Yes, both `flip (.)` and `flip ($)` make sense. As a lens user with quite
abit of existing code, keeping & as-is and adding # is appealing.

In my calculus, 13 in favor, 5 against, 2 not against, 5 don't care or neutral.
I think that this thread is still important.
Hayoo! can't parse "a -> (a -> b) -> b" (bug ?) and if we try to find (&) from Lens, this function has no signature at Hayoo! :) Maybe Hayoo! don't like flipped function application as well. :)) So, I can't say how many packages already have flipped function application.
But I know, that at least one package is already added flipped function application and this package is popular!
Yes, I'm saying abut Edward's "lens" library. As I understand, Edward choose the name looking which name was favorite in a discussion a year ago. An this is good.
(&) it will be de-facto a name for flipped function application if this thread dead.
PROPOSAL: /Data.Function.Flipped/ package
So, maybe "if you can't resist the process, lead it". I mean we still could choose the name.
Who is in favor - we can lead the process not adding function into the base Who is against - you can lead the process with find only one name for flipped function application
*This solution satisfy everyone*: 1) Who is against - we don't add (#) into Data.Function and into the base 2) Who is in favor - we add flipped function application in a package and reserve module name and function name
We all could choose the name and make a little package not in base: Data.Function.Flipped and add here this 1 function or may be 2 (as Andreas Abel suggested).
For example, I prefer (#) = flip ($) and (&) = flip (.)
This case:
g . f $ x == x # f & g
Are you agree?

I think this phrasing is too loaded given the actual numbers. I've counted in this thread, being generous with the +1s (bikeshedding the name counts as an implicit +1) and I find 11 in favor, 7 against and 6 unknown/don't care.
