It's not feasible sometimes.
Yes, they could be considered the same package. But if this results in a
massively huge file then it's impractical. I agree that frequently,
circular dependencies mean the design should be thought through again. But
there ARE some design patterns where it's appropriate (and where merging
the files together would result in a huge file) so I think it's dogmatic to
say that the packages should either be combined or the design should be
re-evaluated. – Matthew Lund Dec 1 '11 at 21:49

print("tree.branch: 'tree.root' in sys.modules ->", 'tree.root' in
Ignore this part - my fault.
