I regret that this is such a silence discussion. In fact Lutger (sorry 
don't know your full name) has implemented a fine QT like thread safe 
Signal Slot library.

// Q_FLAGS, Q_PROPERTY, Q_ENUMS and GUI

--We have, afaik.  no support for isProperty(), and to make 
visual/interactive GUI development possible, isEvent() is also necessary.

-- Now that we know that Compile- to Run- time Reflection could be just 
a mixin template away we have another good reason to ask for more (meta) 
  _traits power.

--Uwe Salomon's Indigo library is also offering a lot of ideas in this 
regard .. one thing I would name here is internationalization.

--QT in D.... ?
D bindings to GUI APIs are already there, but wait ...

I think the point is to give a pure *D2 QT implementation* a go, and 
let's see WHERE the compiler/language is not good enough.

Like Andrei did it for his std.algorithm.
