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.
