For this it could be easier to make a 100% implementation in python or
something like that, for prototyping (or more, i don't believe that
nobody plan this, isn't it ?).

I don't think the goal of furth will be to build a user friendly
interface, but we cannot speak before Tom say what he plan. It's why the
question of furth vs other langages has no sense when we don't know
which task it will do ! My initial question was just to early.
