<p>Les expressions régulières obtenues ne sont pas parfaites :</p>
<ul>
<li>Il faut parfois ajouter le caractère spécial "\b"
(limite d'un mot = position entre un mot et un espace)
à la fin de l'expression régulière.<br>
Vrai pour les mots clés et tous les mots composés des caractères [a-zA-Z_] en général.
</li>
<li>Les délimiteurs "(" et ")" sont à remplacer par "(?:" et ")",
ou voir même être effacé.
</li>
</ul>
<p>...se sont des choses à résoudre à l'analyse réalisé par la <a href="src/wiz/syntax.htm">syntaxe WIZ</a>.</p>
