Instruction: grad_instr_reply_t expr

struct grad_instr_action { grad_entry_point_t expr; /* Entry point to the compiled Rewrite expression */ }; typedef struct grad_instr_action grad_instr_reply_t;

The machine executes a Rewrite expression with entry point expr. Any return value from the expression is ignored. <FIXME> Should the expression receive any arguments? If so, what arguments? I'd say it should take at least the request being processed and the reply pairs collected so far. </>
