Hi list,
I don't understand the following behaviour:
Objective Caml version 3.11.0
# type t = [`A | `B of int u] and 'a u = 'a * t;;
Error: In the definition of t, type int u should be 'a u
# type t = A | B of int u and 'a u = 'a * t;;
type t = A | B of int u
and 'a u = 'a * t
Anyone's got a simple explanation for this ?
ph.
