I think Linus is mostly right. But I don't think this is a reason not 
put the bar very high. Especially with the current state of D. This is 
more about providing a nice, and long, transition process.

The way @property evolve is a good example of what we should do.

An example of management the change (even breaking change) is PHP. PHP 
has so much improved if you consider what have changed between v4 and 
v5, and then v5 and v5.3, that it is a factual proof that breaking 
change can be done to great benefit.
