In a module that might get tangled in a cycle, avoid global code
 that depends on other modules.  Instead of putting such
 initialization at top level, put inside a function that gets
 called after all suspect imports are completed. (That function
 has global keywords ). 

Similarly avoid class attribute initialization at class level, if
 such initialization references higher level modules.
