Description: During the build process, a Context instance is pickled, or at
least attempted to be. This fails because self.node_class is assigned to a
class which is nested inside the __init__() method. Because Python cannot
find this class at unpickling time (i.e. it cannot be imported), Python
refuses to pickle the Context instance, leading to a FTBFS. Since there's no
obvious reason why the class has to be so nested, moving it to a module
global solves the build failure.
