This is exactly why (well, one of the reasons why) star imports are
generally not recommended. There are a small number of modules that
have promised to keep their namespaces clean in order to make this
viable, but even there, it has issues of confusion. There are a few
good places to use star imports, such as when you wrap one module in
another; I would STRONGLY recommend against using two star imports in
a single file, without being VERY sure of what you're doing.
