m could be an instance of the Krayzee class.

py> class Krayzee(object):
...   def __getitem__(self, i):
...     try:
...       r = ['WTF?' for j in i]
...     except:
...       r = 'WTF?'
...     return r
...
py> m = Krayzee()
py> m[1:2:3, 4:5:6]
['WTF?', 'WTF?']
py> m['your moms']
['WTF?', 'WTF?', 'WTF?', 'WTF?', 'WTF?', 'WTF?', 'WTF?', 'WTF?', 'WTF?']
