Thanks, you make some interesting points to consider. This leads me to wonder how these arguments might be extended to
(1) IORef (a,b) vs. (IORef a, IORef b)
depends on whether you need to read/write both variables at the same or different moments. also, "IORef a" may be optimized to "IOURef a" which works faster
(2) TVar (a,b) vs. (TVar a, TVar b)
i never worked with STM, but guess that TVar usage pattern is just the smae as for MVar btw, you can use type synonym to make switching from IORef to MVar easier: type MyVar a = IORef a -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
