OK

By, for instance, invoking a name bound to such as object, much as in
any other language.

When it compiles the function, it does not.  Names, including argument
names, do not have types.  Only objects do.  When you call the
function, see below.

NO<).   *Every* Python object is knows what type it is.  type(object)
queries the object as to its type and returns the response.  Every
argument becomes a reference to an object which the function uses to
get ahold of the object.

If session has method getreply() taking no args, why should it?  (I
doesn't)
