中缀运营商的应用方式？

Question

Is there a way to make applicative uses of <$> and <*> look nice when dealing with infix operators? I think that

((++) <$> a <*> ((++) <$> b <*> c ))

looks much more cluttered then

a ++ b ++ c

so I wonder if there is a nicer way.

Answer 1

(<++>) = liftA2 (++)
a <++> b <++> c

or

liftA2 (++) a $ liftA2 (++) b c

Answer 2

请参阅Thomas Davie的InfixApplicative软件包，它提供了一般的语法技巧，而不必为每次提升定义一个新的运算符。

Answer 3

SHE lets you write

(|a ++ (|b ++ c|)|)

if that's any use. Of course, there's some overhead to introducing a preprocessing layer.
