Given »class A { void foo() const {} }; A a = new A;«,
»typeof(&a.foo).stringof« yields »void delegate() const«.

However, trying to declare a delegate variable of this type like »void
delegate() const dg; dg = &a.foo;« fails with »const/immutable/shared/inout
attributes are only valid for non-static member functions« or, depending on the
scope one tries to declare the variable in, even more cryptic error messages.
