Useful notes:
- Use `opaque` if you need to handle any kind of C pointer.
- Use `string` to handle C `const char*` (`symbol` is strictly used to represent Scheme symbols).
- `thread-data` is a special type used to pass the current thread's `gc_thread_data` instance to a C function. These objects are passed implicitly when making a Scheme function call.
- `thread-data` is a special type used to pass the current thread's `gc_thread_data` instance to a C function. These objects are passed implicitly when making a Scheme function call. For example:
(c-define sub-big-nums bignum "sub_big_nums" thread-data bignum bignum)
(sub-big-nums
