Function name as text

[Craig Black]

I have been considering porting some C++ code to D.  One of the classes I 
would have to port is an event queue class where each event on the queue has 
a delegate and a text string that points to the function name that the 
delegate refers to.  The function name is used to visualize the event queue 
for run-time debugging purposes.  It is important to capture both the class 
name and the function name as text.

In C++ I had a macro called DISPATCH that used the stringize operator # to 
capture the name of the function.  The good (and bad) thing about C++ in 
this case is that when specifying a pointer to a member, you must fully 
qualify the function name, so you would have something like this.

class Foo {
public:
  void bar() {}
};

Foo *foo = new Foo;
Event event = DISPATCH(foo, &Foo::bar);

Using the stringize operator, the DISPATCH macro could capture the text 
string "Foo::bar" as well as the member function pointer.  Here is the 
equivalent code in D..

Foo foo = new Foo;
Event event = dispatch(&foo.bar);

Which is much more elegant, except that I can't figure out a way to capture 
the name of the function and it's class.  I tried fiddling with the stringof 
operator but that doesn't seem to work.

Any ideas?
