[Python-Dev] A Hygienic Macro System in Python?

Just throwing out some thoughts.

There are several possible use cases for new customizable syntax:

- resource allocation (lock.acquire(); try-finally: lock.release())

- defining functions with special treatment (e.g. classmethods, properties)

- defining class-like things (e.g. Zope-style interface declarations)

Maybe it's possible to invent a new statement that covers all of
these?  Certainly a macro system should support doing all these
easily...
