Decorators: J2 and a relation to @

[Shane Holloway (IEEE)]

Decorators.  Yep, in your inbox again.  I'll be short about it.  But 
first, I should put out a disclaimer: I'm not opposed to the pie-syntax. 
  I'm just tired of writing my method names three times, and having the 
important 'classmethod' below the function.

Now... on with it!

 From the example in Section II, part 3 of 
http://www.aminus.org/rbre/python/pydec.html consider the following 
decorated function.

     @using([
         funcattrs(author="Guido van Rossum"),
         memorize,
         synchronize,
         classmethod,
     ])
     def foo(cls, *args):
         pass


This looks an lot like the suite method proposed in J2 in the current 
syntax of Python 2.4a2.  All that would need to be added is a "using" 
decorator method.  I like the @ because it makes me take note that the 
following is special in terms of code execution.[*]

What do you think?

[*] I could actually see @ being used to introduce smalltalk/ruby-esk 
block closures... but that's a totally different discussion for a much 
different time.  <1.2-wink>
