I have threaded this as a default argument in this PR so that the diff looks sane, and have tried breaking up the changes in sane commits. Adding it as a non default parameter can be a trivial follow up PR.

However, I am not really happy with this solution. This can be rewritten as an ast visitor as well for which I have a pretty sane implementation already.
