'self.x' would collide profoundly with the convention of using 'self' for
the instance-argument in bound methods.
Here, foo.x assumes that 'foo' is not rebound in the context of the def -
the class, module, function, or wherever it's defined. That seems like an
unnecessarily too strong an assumption.
Both of these things suggest to me that we don't want to use a magic
variable name, but rather some kind of builtin function to get the object
(lexically) containing the block.
It's tempting to name it something like 'this()', but that would be much
too easily confused in methods with 'self'.
Since we're looking for the lexically containing object, i'd call it
something like current_object().
class Something:
"""Something's cooking, i can feel it."""
def help(self, *args):
"""Spiritual and operational guidance for something or other.
Instructions for using help:
..."""
print self.__doc__
print current_object().__doc__
if args:
self.do_mode_specific_help(args)
I think i'd be pretty happy with the addition of
__builtins__.current_object, and the allowance of arbitrary metadata with
functions (and other funtion-like objects like methods).
