I often use the following idiom for methods in Leo:
def spam(self,...):
v = self
# Now use v instead of self
The idea is to use one-letter codes for common classes. Leo uses c for
"commanders", f for frames, t for Tk.Text widgets or "tnodes", v for
"vnodes", u for "undoer" objects, etc. With this idiom, objects of the
class in which the method exists are handled just like all other objects.
It saves typing and makes the type of all objects clear.
One could use:
def spam,(v,...):
# etc.
instead, but that would violate the coding guidelines (and pychecker would
complain by default).
This scheme is simple, clear, concise, effective. It has no drawbacks that
I know of.
