Extending Python Syntax with @

> @x @y @z  -- short for instance variables in a method definition

This is completely unnecessary.  Leo uses the following convention:

def whatever(self):
  v = self
  v.whatever

The assignment v = self (or x = self etc.) indicates the expected type of
self and saves keystrokes.  This convention has been useful in refactorings
when moving methods from one class to another: all that had to be done is to
change the v = self line to something else.

BTW, it would also be possible to define the function as follows:

def whatever(v):
  v.whatever

However, this isn't proper Python style and Pychecker complains.
