is possible f# have function composition between operators.not , standard .net function, instance string.isnullorempty ? in other words, why following lambda expression unacceptable: (fun x -> not >> string.isnullorempty) the >> function composition works other way round - passes result of function on left function on right - snippet passing bool isnullorempty , type error. following works: (fun x -> string.isnullorempty >> not) or can use reversed function composition (but think >> preferred in f#): (fun x -> not << string.isnullorempty) aside, snippet creating function of type 'a -> string -> bool , because ignoring argument x . suppose might want just: (string.isnullorempty >> not)
