NameError with case classes

[msha...@twitter.com]

I am unable to get case classes to work correctly on my machine. I am running this on Windows with Python 2.7.6 32-bit (have tried 2 different python installations):

In [14]: from macropy.case_classes import macros, case
In [15]: @case
   ....: class Point(x,y):
   ....:     pass
   ....:
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
<ipython-input-15-82da36e76a20> in <module>()
      1 @case
----> 2 class Point(x,y):
      3     pass
      4
NameError: name 'x' is not defined

I tried to run the example as well:

----> 1 import examples.using_macros.target
C:\macropy-master\docs\examples\using_macros\target.py in <module>()
      2
      3 @case
----> 4 class Point(x, y): pass
      5
      6 p = Point(1, 2)

NameError: name 'x' is not defined

For fun I also tried show_expanded:

In [13]: with show_expanded:
   ....:     @case
   ....:     class Point(x,y):
   ....:         pass
   ....:
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-13-32d9ae40feb8> in <module>()
----> 1 with show_expanded:
      2     @case
      3     class Point(x,y):
      4         pass
      5
AttributeError: __exit__

Any help would be appreciated.

Thanks,
Matt

You need to do an 

import macropy.console

if you want to use macros in the console, or 

import macropy.activate

if you want to use macros in the files you are importing. Note that you cannot use macros in the same file you activate them, so you may need a simple "run.py" file which activates macros and imports the "real" application
