Subject: Constraints in module types
Date: Thu, 19 Jan 2006 11:53:27 +0100 [thread overview]
Message-ID: <43CF6FA7.8040604@barettadeit.com> (raw)
# type foo = [ `Foo of foo ];;
type foo = [ `Foo of foo ]
# module type BAR = sig type bar constraint bar = [ > foo ] end;;
The type constraints are not consistent.
Type bar is not compatible with type [> foo ]
Is there a good reason for prohibiting the above declarations? Could I achieve a
similar effect with private row types?
Alex
