Casting to a superclass

Hello, all.

I'm writing a utility class, which will have an NSMutableSet as an ivar. I want users of the class to be able to access the set, but as an immutable object.
So, can I typecast the NSMutableSet to NSSet, or should I just return [NSSet setWithSet:someSet];?

Thanks,

-- Rob
