I ran into the problem that there's no way to get a list at compile
time (or even run time for that matter) of the members of a class. Nor
is there any way to operate on types in place.

I'd like to be able to create something like decorators in python that
operate on function and class definitions in place where:

@MyDecorator
class MyClass {
...
};

translates into

class MyClass_{
...
};

typedef MyDecorator<MyClass_>::type MyClass;

Or

@MyDecorator
int f() {
...
}

translates into

int f_() {
...
}

void f() {
  return MyDecorator<f_>::value();
}

So for instance, I could have a decorator that performs logging
(although I'd need some kind of stringize for that for that as well).

Probably this isn't the right tool for that. Especially since it seems
like it would be hard to use in production if I can't use the stl and
boost.

Thanks anyway,
Brendan
