Hi,

I don't know ObjectiveC, but about Python, even if there is no direct 
wrapper, it couldn't be difficult. Indeed, all the C API in Python use 
Pointers, so you just have to create your own wrapper like this:

type PyObject_Ptr is new System.Address;

function A_C_Function_Wrapper_To_Python(pyobj: PyObject_Ptr; ...) return 
SomeType;

And so on. I did for MySQL and it's not a big deal, some times of 
course, you could have to write a littke C code to help you and bind 
your ada program with if (particularly when you want to access to 
structure field when you are not sure of the structure size, otherwise, 
you can still create the equivalent Ada Structure and map).

I'm still thinking that everything than can me wrapped in C can me 
wrapped in Ada even if it's, the first time, a little bit more 
complicated but not so much.
