Note, just looked at the conversion functions and using the ID prefix
is not consistent in the BGE, Scenes and IPO's ignore the prefix.

Unless we agree on any changes this is ofcourse how it should stay.
But with 2.5 being the next big thing, we can plan updates for the BGE
too. Im happy to do the python 2->3 update whenever we switch over.

I guess we can agree that removing these in 2.5+ is OK, even if they

if your OK with this then so am I, but "shouldn't break scripts (at
least not much)." is as good as breaking scripts IMHO. eg, doing most
things with the resulting object will break scripts.
obname = act.getObject()
ob = scene.getObjectList[obname]
