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

2002年3月19日 19:32:22 -0500

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...
