Re: Record of STRefs better than STRef to a Record?

G'day all.
...
If I use an STRef to a record, will a new record be created each time I
want to update a single field?
Basically, yes.
Ok.

Right now I'm using a record of STRefs, like:
data E s = E{
      refi ::  STRef s Int,
      refc ::  STRef s Char
    }
You could always use IORefs, if you don't mind having the IO monad
threaded through.
I'm using the Lazy version of ST with a monadic version of iterate to return 
an infinite list of values. Can't do that with IO...

Thanks,
