AFAIK you are allowed to shadow just about anything in implementations. If you wanted to keep the exact same interface but retain the ability to avvoid the shadowing issue on the labels you could do:
module Foo = struct type t = Foo end type foo = Foo.t = Foo module Foo2 = struct type t = Foo | Bar end type foo2 = Foo2.t = Foo | Bar HTH, Till On Mon, May 31, 2010 at 10:46 AM, Jacques Carette <care...@mcmaster.ca> wrote: > type foo = Foo > let x = Foo > > type foo2 = Foo | Bar > let y = Foo > let z = (x,y) ;; > > I thought that re-using of algebraic labels was not allowed - but apparently > it is?
