I like this.

I'm not too thrilled about this... AST nodes are effectively immutable anyway, so passing them around with pointers-to-const is just unnecessary typing. Although there are a few places where we pass around "const Expr*"'s, most of the time we don't bother with const, and I don't think it's useful to const'ify this code.

Very nice.

Could you submit this patch without the const changes?
