ocaml-infer-let-rec pre-binds the function name to a fresh tv before
inferring rhs (which may recursively call the name), unifies the
inferred rhs type with the tv, generalizes, then infers body.
Builtin env types :: : 'a -> 'a list -> 'a list and @ : 'a list ->
'a list -> 'a list — needed because :op compiles to (:app (:app (:var
OP) L) R) and previously these var lookups failed.
Examples now infer:
let rec fact n = if ... in fact : Int -> Int
let rec len lst = ... in len : 'a list -> Int
let rec map f xs = ... in map : ('a -> 'b) -> 'a list -> 'b list
1 :: [2; 3] : Int list
let rec sum lst = ... in sum [1;2;3] : Int
