I don't want to be a naysayer but I think it's a horrible idea.
I've had numerous problems with the current implementation of atom/bond
iterators, if they are going to remain the only way to loop through
atoms/bonds it will be very difficult if not impossible to manipulate
OBMol to the degree that I need.

I would urge leaving things that work well enough alone and concentrate
on fixing stuff that's broken - for example 2.3.1 broke static
compilation on OSX and MinGW yet again, I haven't heard back any
comments regarding that.
