+PEP 3155: Qualified name for classes and functions
+==================================================
+
+:pep:`3155` - Qualified name for classes and functions
+ PEP written and implemented by Antoine Pitrou.
+
+Functions and class objects have a new ``__qualname__`` attribute representing
+the "path" from the module top-level to their definition. For global functions
+and classes, this is the same as ``__name__``. For other functions and classes,
+it provides better information about where they were actually defined, and
+how they might be accessible from the global scope.
+
+Example with (non-bound) methods::
+
+ >>> class C:
+ ... def meth(self):
+ ... pass
+ >>> C.meth.__name__
+ 'meth'
+ >>> C.meth.__qualname__
+ 'C.meth'
+
+Example with nested classes::
+
+ >>> class C:
+ ... class D:
+ ... def meth(self):
+ ... pass
+ ...
+ >>> C.D.__name__
+ 'D'
+ >>> C.D.__qualname__
+ 'C.D'
+ >>> C.D.meth.__name__
+ 'meth'
+ >>> C.D.meth.__qualname__
+ 'C.D.meth'
+
+Example with nested functions::
+
+ >>> def outer():
+ ... def inner():
+ ... pass
+ ... return inner
+ ...
+ >>> outer().__name__
+ 'inner'
+ >>> outer().__qualname__
+ 'outer.<locals>.inner'
+
+The string representation of those objects is also changed to included the
+new, more precise information::
+
+ >>> str(C.D)
+ "<class '__main__.C.D'>"
+ >>> str(C.D.meth)
+ '<function C.D.meth at 0x7f46b9fe31e0>'
+
