Most likely not, there are being made up right now.
f = sort.nub
is different from
f x = (\x -> sort.nub x)
f = sort.nub.id
f = sort.nub.id.id.id.id.id.id
, and such behaviour would confuse the hell out of me as well as
seriously hurt my sense of semantic aesthetics, even if it's just
no-ops. Or the same lambda term, which is exactly my point.
