(You may already have thought of this, but it just occurred to me and I figured I would open an issue.)

The source transformation approach you use here has the downside that it links keywords that might otherwise be separated. Consider the keyword in in Python. This is used to check for membership in iterables and also as part of for expressions. But I think that these two uses don't have anything to do with each other. An expression like for x in s: f(x) is parsed into an AST object with target, iter, and body fields (and orelse, but nobody uses that), and at that point the in helper keyword is gone.

Now, suppose you wanted to use dans as the helper for pour, but appartient to check for membership:

pour nombre dans intervalle(100):
    si nombre appartient premiers:
        imprime(nombre)

I don't think that would be possible here. Is there any way around it?
