Perniciously stolen on the OCaml CVS server (file "Changes"), but I lack
the new doc ;-):
Objective Caml 3.01:
--------------------
New language features:
- Variables are allowed in "or" patterns, e.g.
match l with [t] | [_;t] -> ... t ...
- "include <structure expression>" to re-export all components of a
structure inside another structure.
- Variance annotation on parameters of type declarations, e.g.
type (+'a,-'b,'c) t (covariant in 'a, contravariant in 'b, invariant in 'c)
