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.
