/* --- Token appending
 * The core problem is that we want an interface where we can append {instructoin}
 *  tokens without modifying the counter as that gets old fast and error prone
 *  when doing batches.
 * Many tokens are enumerated so we have to push them individually.
 * A variadic argument interface would be ideal except theres not free
 *  value to use as a termination and i dont need to tell you why passing the count
 *  by hand is a terrible idea.
 * Enter macro magick, the below horror beyond your comprehension will count
 *  the arguments and pass them explicitly, in an implicit way.
 * Now:
 *  append_instructions(...);
 * Is valid and human error resistant.
