We definitely don't want to scare off developers with right-angled 
triangles - systems programming already has an unfortunate reputation 
for being difficult and scary, and as an open source project we need to 
do everything we can to make it easier for people to join our community.

This should probably head to stable - we don't want people being scared 
off when submitting bugfixes to the stable tree.
