Hi, camlp4 seems to break parsing of object duplication on 3.11. Can anyone
replicate this problem? Is this an known issue? A quick google search did
not reveal anything..

I only know of the brute force update which is less than desirable:
class test (x : int) = object
val a = x;
val b = x;
method add (d:int) =
let copy = {<>} in
let arr : int array = Obj.magic copy in
arr.(2) <- arr.(2) + d;
arr.(3) <- arr.(3) + d;
copy
method print = Format.printf "%d %d" a b
end
But my brain is fried and I can't think of a nicer way..

Nope, I didn't see a satisfactory workaround. Luckily I didn't need
camlp4 in those modules anymore, so I only reported the problem,
corrected the Makefile to skip them, and moved on.
