Name changes have been the least annoying breaking change I've 
come across from using D. Language design being the biggest.

Luckily I've expected that, and recently hit has been very 
infrequent. There are still changes that will be making big 
ripples (actually maybe not so much if we are changing how we 
handle toHash...). Maybe this unstable branch thing will allow us 
to make a bunch of a breaking changes together when we have one 
of these required disruptions.
