hello,

What are the rules for applying a function to its arguments ?

# let g f i = f i;;
	val g : ('a -> 'b) -> 'a -> 'b = <fun>

# let rec f0 x   = fun i -> (f x) i;;
	val f0 : 'a -> 'b -> 'c = <fun>
# let rec f1 x i = (f1 x) i;;
	val f1 : 'a -> 'b -> 'c = <fun>
# let rec f2 x   = g (f2 x);;
	val f2 : 'a -> 'b -> 'c = <fun>

# let a = f0 ();;
	val a : '_a -> '_b = <fun>
# let a = f1 ();;
	val a : '_a -> '_b = <fun>
# let a = f2 ();;
	Stack overflow during evaluation (looping recursion?).

I expected f0, f1 and f2 to be equivalent,
but,  f0 and f1 look like ['a * 'b->'c)]
and f2  looks like ['a->('b->'c)]

Is it a normal feature ?
