Re: [Haskell-cafe] polyvariadic function for Applicative instances

Maybe this is what you are looking for: http://www.haskell.org/haskellwiki/Idiom_brackets -chris On 9 mei 2010, at 18:39, Xiao-Yong Jin wrote:

Hi,

Is it possible to have a function accept variable number of arguments, such that 'f' can be instantiated to different concrete types as

f :: Applicative a => (e1 -> f) -> a e1 -> A f f g a = pure g <*> a

f :: Applicative a => (e1 -> e2 -> f) -> a e1 -> a e2 -> A f f g a b = pure g <*> a <*> b
