Hello,

I'm wondering why record declarations can't be part of a regular
variant type declaration. Eg, is there a special reason that this
is illegal:

type expr = 
  | Fun of {formal: string; body: expr}
  | App of {func: expr; arg: expr}

and I must write: 

type expr = 
  | Fun of fun_expr
  | App of app_expr
and fun_expr = {formal: string; body: expr}
and app_expr = {func: expr; arg: expr}

IIRC the first version is ok in SML. Why the difference in Caml?
