I've noticed quite a few pages referencing constructs such as:
var :: MVar ([Foo]) var = unsafePerformIO (newMVar ([]))

If I remember correctly, you "should" put {-# NOINLINE var #-} on a line just before that.
Having a reliable way to create a piece of global state would be very convenient.
This is well known and extensively discussed - unfortunately it is a complicated (or at least controversial) issue Isaac -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFF7fiFHgcxvIWYTTURAoMXAJ9SCryCX+daNLKrMIhWlMh/aJmVXwCghosx 6/lBweYnNslHLal57RAtX0Y= =2oIN -----END PGP SIGNATURE-----
