here's simplified code : type t1 = [ `a of t2] , t2 = [ `b | t1 ] i know in case don't need "and" because types don't need mutual definition, in real world need it. why doesn't work ? can make work doing and t2 = [`b | `c of t1] but lose interest of polymorphic variants , i'll switch normal variants. is there way can ? in definition of t2 trying "extend" type t1 not defined @ point (as requre t2 in `a branch). if want "emulate" recursive ordinary data types (but using polymorphic variants instead) should use references mutually-recursive types under data constructor. example in case may this: type t1 = [ `a of t2 ] , t2 = [ `b | `c of t1 ] note in ocaml construction [ `b | t1 ] not mean extending polymorphic row row - type synonym substitution.
