Little by little, MTASC is getting better. It doesn't take too much of my time and it should reach soon 1.0 . Recent talks on the mailing list are about ECMAScript compliance. MTASC could be better compliant than Flash compiler, but users could not anymore compile their old AS2 code withing making it ECMA compliant. That's why right now I'm focusing on changes that doesn't break MTASC safety or design, but still are keeping maximal backward compatibility with Macromedia compiler. Realistic over Idealist (well if I was not pragmatic I wouldn't have chosen AS2 !).
