Actually, wouldn't streams be an example of good Liskoviness? If there
was a readonly stream base class, and a readwrite subclass, //that//
would violate the immutability implied by a reference to a readonly
stream. Having canwrite==false on the other hand means you're using a
type which may have writable implementation.

Hi Kelly,

   I'm not all that familiar with the streams library.  Would you mind
