[racket] C++ Extensions and Classes

> Class Foo looks like this:
>
> Foo {
>      func1() { /* ... do stuff */ }
> }
>
> Class Bar looks like this:
>
> Bar : Foo {
>      func2() { /*... do more stuff /*}
> }

> I've currently written a single .cpp racket extension that creates Bar and
> creates the extensions for both func1() and func2(); however, I'd like to
> create two racket extension classes. One extension that does only functions
> inside Foo and then I just want to include Foo_ext.h (my racket extension
> to Foo) in Bar_ext.h so I have access to all the functions.

> So I currently have this:

> Bar_ext.cpp:
>
> func1_racket_ext() { /*... do racket stuff and run func1() */}
>
> func2_racket_ext() {/* ... do more racket stuff and run func2() /*}
>
> /* Scheme initializers etc... */

> Foo_ext.h:
>
> func1_racket_ext() { /*... do racket stuff and run func1() */}
>
> /* Scheme initializes etc... */

>
> Bar_ext.cpp:
> #include "Foo_ext.h"
>
> func2_racket_ext() {/* ... do more racket stuff and run func2() /*}
>
> /* Scheme initializers etc... */

> Is this even possible? I feel like namespace might be an issue. This would
> be extremely useful for me because it would allow me to not write lots and
> lots of redundant code since I have many classes that use class Foo as a
> super class.
