I am pretty sure, it is possible to implement them with camlp4. Just a
matter of time -- and motivation.
The only limitation I can see, is that the generated constructors won't
be capitalized. E.g.:
type t = MyConstr | YourConstr of int
=>
type t = MyConstr | YourConstr of int
let myConstr = MyConstr
let yourConstr i = YouConstr i
