   Isn't the requirement too strong? When I need a file-like object I
seldom need more than .read() and .write() methods, and even of those I
seldom need both at once -- I usually need one or the other.
   Testing for strict conformance is not duck typing IMO -- it's
interface.

           Programmers don't die, they just GOSUB without RETURN.
