Oh, OK.  I'm against (mandatory) type declarations.  However, I do
believe that the object's type should have to include the expected
interface for the method invocation to succeed.  I'm not arguing for
mandatory enforcement of that "should" in Python itself, but rather
for a clear language so that the provider of a value and the user of a
value can communicate about what's expected and/or required by the
logic of the program.
