Revoir les free dans le parser a cause de ast_destruct qui rentre dans les fils.

il faudrait ecrire des fonctions qui ne le fasse pas! Voir aussi au niveau de la

boucle general si ast_destruct est appele alors qu'une erreur de parse est surevenur

(le cas echeant, le supprimer)

----

Voir probleme de syntax que j'accepte lorsque un EOF apparait avant une quote

fermante. Le token est valide alors que sous bash non

----

ajotuer le prompt PS3 lorsque l'on parse sur plusieurs ligne

----

parse du case
