If you have a function: compare : Date -> Foo -> Bool
you can then do: compareWithDate = compare date
and in your filter use compareWithDate:
compare : Date -> Foo -> Bool
compare .....
filterFoos : List Foo -> Date -> List Foo
filterFoos foos date =
let
compareWithDate = compare date
in
List.filter compareWithDate foos
