/* ZL uses the "tagged va_list" approach:
To facilitate data transfer to a different programming system, it
supports a generic data structure modeled after Lisp tagged lists.
* Lists are encoded using a standard datastructure: va_lists. This
prevents re-invention and makes it very easy to use on both the
sending and receiving end.
* Tags are encoded as const char *. This allows fast C pointer
comparisons and makes bridging to interned symbols (hashed
strings) common in dynamically typed languages. */
