I am not working on that currently. > Also, I was wondering how tree-specific the random forest module is. > I looked at the pull request but could not find much about this. > Was there any discussion on this that I missed?

The current implementation is not that much tree-specific, but I implemented some optimizations in my pending pull requests #478 and #491 that makes the BaseForest class highly tree-specific. > Or do you think that bagging is so easy to implement that it > does not pay off to have an extra meta estimator? I think meta-estimators would a good thing to have and that much of the forest code could be reused to implement a bagging meta-estimator.
