 XPCOM would need to rename {{{print}}} to something else, e.g.
 {{{print_}}}. I'm not sure how feasible it is to get that fix rolled out
 to the distributions that still ship a python-xpcom we can use in the
 first place (Ubuntu doesn't ship it at all and recent versions of Fedora
 are [ticket:2772 broken], too).

 As expected, this still fails in getattr():

 {{{
         setattr(print_iface, 'print_', getattr(print_iface, 'print'))
 }}}

 {{{

   File "<XPCOMObject method 'print'>", line 2
     def print(self, Param1, Param2):
             ^

 }}}

 The problem is that the code generated on-the-fly by '''python-xpcom'''
 uses the reserved keyword {{{print}}}.
