 > no problem. You can just add this to the existing branch. I am no longer
 active on this ticket. Maybe it would be a good time to get it into sage,
 as a good first step, even if it does not implement everything suggested.

 You are free to split it into several tickets.

 Quick remark on the code: some of the constructors do not accept
 `exact`/`base_ring` as arguments. I know that some of them are infinitely
 slow with `exact=True`. There are already some of them that have default
 `exact=False` that is fine with me if there is a clear warning.

 PS: I have code that improves the generic double description algorithm and
 makes the constructions reasonable over QQbar... but it needs a bit of
 cleaning.
