But given that such users can still obtain the same features 
(auto-completion, etc.) through usage of constants:

class Foo(QObject):
     SIG_FOO_1 = SIGNAL("foo(QString*)")
     SIG_FOO_2 = SIGNAL("foo(const QString &)")

What is exactly the advantage of supporting this feature out-of-the-box 
in PyQt?
