How do you handle heterogeneous reads? e.g.

ubyte[] x = new ubyte[](4);
inp.read(x);
ubyte[] y = new ubyte[](100);
inp.read(y);

Having input stream types which aren't runtime type compatible is kind 
of a sucky situation. That's what the interfaces are for, and that's 
what the wrapper provides for  e.g. input streams which are structs.
