Original bug ID: 6615
Reporter: ggole
Assigned to: @garrigue
Status: closed (set by @xavierleroy on 2016-12-07T10:36:50Z)
Resolution: fixed
Priority: normal
Severity: minor
Fixed in version: 4.03.0+dev / +beta1
Category: ~DO NOT USE (was: OCaml general)
Monitored by: @gasche @hcarty

Bug description

The syntax of inline records doesn't seem allow a trailing ; as in normal records, that produces a parse error. However, inline records are printed with exactly such a trailing ;.

In short:

# type t = T of { f : float; };;
Characters 27-28:
  type t = T of { f : float; };;
			 ^
Error: Syntax error
# type t = T of { f : float };;
type t = T of { f : float; }

Hopefully the trailing ; will be allowed. It would be pretty surprising if the syntax were different to regular records.

Steps to reproduce

Enter

type t = T of { f : float };;

into a 4.03 toplevel.
