Many thanks to all who have suggested various languages to study. However,
python already has all the language features I have ever wanted. I'm not
looking for a better language, I'm looking for better ways to use python.
So I am looking for patterns that I can transfer from other languages to
Leo's python code base.
Vitalije has already opened my eyes to the benefits of stateless code. The
new version of at.writeAll in the at-others branch highlights this
pattern. Here is the essence of the new at.writeAll:
files, root = at.findFilesToWrite()
for p in files:
at.writeAllHelper(p, root)
Splitting the task this way is a big step forward. The new
at.findFilesToWrite method disentangles a computation that used to require
complex state in at.writeAllHelper.

P. S. Conversely, Leo's code contains anti-patterns that are holdovers from
its C language days. For several years I have been replacing index-based
computations (g.skip*) with regex's when I revise code.
There are also some Python anti-patterns, including the g.TypedDict
classes. Now that Leo requires Python 2.6+, the code could use subclasses
of dict.
