same than List.return but exceptionless
val map_opt : ('a -> 'b option) -> 'a list -> 'b list and List.filter in one round
val assoc_err : 'a -> ('a * 'b) list -> err:string -> 'b
same than List.assoc but with a custom error message
val assoc_def : 'a -> ('a * 'b) list -> def:'b -> 'b
same than List.assoc but with a default value
val assoc_replace : 'a -> 'b -> ('a * 'b) list -> ('a * 'b) list
replace the associated value for the first key in an association list
