I think reflection in general is very different from reflection for a GUI.

When you have a GUI control, you want to apply reflection for a few of 
its properties. You won't have #ifdefs (or at least I would consider it 
bad design). Case in point: its interface should be extremely simple and 
easy to parse.

You shouldn't need complex information like reflection for virtual 
functions, overloading etc.

Even reflected property types should be of trivial types:
1. build in types
2. std::string
3. types that can simply be read from /written to strings.

For case 3., you might also have a validation function which will be 
used in design-mode to validate user input.

At least that's what I want.

Best,
John
