|
* List processing operations.
|
|
*
|
|
* The general idea here is that a list processing operation is a
|
|
* function which takes two arguments, both cons_pointers:
|
|
*
|
|
* 1. args, the argument list to this function;
|
|
* 2. env, the environment in which this function should be evaluated;
|
|
*
|
|
* and returns a cons_pointer, the result.
|
|
*
|
|
* They must all have the same signature so that I can call them as
|
|
* function pointers.
