While I don't think we need to worry so much at the moment
about breaking binary compatibility with new D releases, we do
have a big problem with breaking source code compatibility.
This is why we need to have a VERY high bar for breaking
changes.
I don't think it is that straightforward to conclude anything
about source compatibility in a programming language from this
argument about binary compatibility in a kernel.
