Hi Poor Yorick,


Yikes!  You're right; the code is totally doing the wrong thing.  Thanks
for catching me on that one.


This should be one way to correct it:

###
     def __init__(self):
         try:
             self.impl = _GetchWindows()
         except ImportError: pass
         else:
             self.impl = _GetchUnix()
###


If that looks good with you, let's put a comment on that recipe with the
correction.


Thanks again!
