I think that's the key issue here. I find that when code is well
structured, you pretty much never have a need for global statements,
By the way, the Thesaurus class reminds me of using the old recipe
b = Bunch(x=1) b.stuff = Bunch(y=2)
I've also seen an answer on StackOverflow that uses automatic recursive
I've seen another variation of recursive bunching, I think it was by
Alex Martelli on StackOverflow, but I can't find it now, I believe it
used defaultdict as part of it..
This approach can be handy sometimes but has drawbacks, as others have
I think the issue is that it's not a "solution for avoiding globals",
which is not a problem in need of solution, but this can be a quick and
dirty way to organize a few levels of dicts/Bunches and usually people
come up with a custom variation on these recipes that suit their
