Years later, my Python and software mana...

  ...class. A function object contains a reference to the function's 'globals' object, which is the __dict__ of the module that defines it. Since the __dict__ normally has a reference to the function there's a cycle that needs to be broken, or else the __dict__ would never be garbage collected. Note that a reference-count based solution doesn't work within one module, since references between functions are by name, not by value -- two mutually recursive functions can still both have a ref...

Importing * From a Package; the __all__ Attribut...
