1232 | * On ne prends que les newbinding ou returned_any_state est vrai. |
1233 | * Si ca ne donne rien, on prends ce qu'il y avait au depart. | |
ae4735db | 1234 | * Mais au nouveau depart de quoi ? |
34e49164 | 1235 | * - si ca donne rien apres avoir traité toutes les fonctions avec ce binding ? |
ae4735db | 1236 | * - ou alors si ca donne rien, apres avoir traité toutes les fonctions |
34e49164 | 1237 | * avec tous les bindings du round d'avant ? |
ae4735db | 1238 | * |
34e49164 C |
1239 | * Julia pense qu'il faut prendre la premiere solution. |
1240 | * Example: on a deux environnements candidats, E1 et E2 apres avoir traité | |
1241 | * la regle ctl 1. On arrive sur la regle ctl 2. | |
1242 | * E1 ne donne rien pour la regle 2, on garde quand meme E1 pour la regle 3. | |
1243 | * E2 donne un match a un endroit et rend E2' alors on utilise ca pour | |
1244 | * la regle 3. | |

34e49164 C |
1246 | * I have not to look at used_after_list to decide to restart from |
1247 | * scratch. I just need to look if the binding list is empty. | |
1248 | * Indeed, let's suppose that a SP have 3 regions/rules. If we | |
1249 | * don't find a match for the first region, then if this first | |
1250 | * region does not bind metavariable used after, that is if | |
1251 | * used_after_list is empty, then mysat(), even if does not find a | |
1252 | * match, will return a Left, with an empty transformation_info, | |
1253 | * and so current_binding will grow. On the contrary if the first | |
1254 | * region must bind some metavariables used after, and that we | |
1255 | * dont find any such region, then mysat() will returns lots of | |
1256 | * Right, and current_binding will not grow, and so we will have | |
ae4735db | 1257 | * an empty list of binding, and we will catch such a case. |
34e49164 C |
1258 | * |
1259 | * opti: julia says that because the binding is | |
1260 | * determined by the used_after_list, the items in the list | |
1261 | * are kind of sorted, so could optimise the insert_set operations. | |
