Askar,
We all have ideas about what we should do in Bison, and some of them are in
TODO. You are welcome to become a contributor. I have been willing to have
such a feature for years.
Pay attention though that what often appears as simple, is much more delicate
than you might think when you have to turn it into a fully blown feature for
everyone.
Please, contribute a specification, or better yet, a first implementation, to
see how we should do it.
