Maybe "@" and "^" are right-associated.
# let ( ^$ ) f x = f x;;
val ( ^$ ) : ('a -> 'b) -> 'a -> 'b = <fun>
# print_string ^$ List.fold_left (fun x sum -> sum ^ x) "" ^$ ["1";"2";"3"];;
321- : unit = ()
# let ( @$ ) f x = f x;;
val ( @$ ) : ('a -> 'b) -> 'a -> 'b = <fun>
# print_string @$ List.fold_left (fun x sum -> sum ^ x) "" @$ ["1";"2";"3"];;
321- : unit = ()
