Subject: Question about type unification
Date: Mon, 26 May 2008 13:22:04 +0100 [thread overview]
Message-ID: <20080526122204.GA6727@annexia.org> (raw)
With this definition:
type 'a t = float
Why is this allowed?
# ((3.0 : unit t) : string t) ;;
- : string t = 3.
Note that unification is prevented if t is opaque, eg, hidden behind a
module signature.
Rich.
