Well, you have to define a langauage construct before you
can implement anything at all.  It's not a core library vs
IP-specific library issue.

Yes, decorators could probably serve that purpose.  I haven't been
following CPython since 1.6, but I understand that decorators have
been added or are being added to an upcoming release.  Can you
decorate parameters, also, or just functions and classes?  Ideally,
you'd want to decorate a parameter with its type, otherwise you're
back to a syntactical issue.

Can you point to an example in pyobjc?  I tried to find something
on the site, but I got too irritated at their slow-rendering header
and gave up.  From what I remember about ObjC, though, the
language supports sending messages to objects without knowing 
anything about the object.  This is a lot more compatible with
the Python object model than the C#/VB model, where everything
is strongly typed.
