Subject: [Caml-list] Mutability analysis too strict?
Date: Sun, 9 Dec 2001 14:14:19 +0200 [thread overview]
Message-ID: <OF2334A0F2.3D939797-ONC2256B1D.00427F44@telaviv.ibm.com> (raw)
List,
I have a problem with the mutability analysis for hash-tables.
For example:
let h = Hashtbl.create 10 ;;
creates:
h : ('_a, '_b) Hashtbl.t
instead of:
h ('a, 'b) Hashtbl.t
My specific hashtable contains immutable objects that can be added
and removed to the table. The default analysis is too strict, forcing me
to use Obj.magic for coercion ('_b -> 'b). This is safe in this case,
because I know
the objects are immutable. However, in the general case, I don't see
why it is neccessary.
Anyone cares to explain?
Ohad.
