The Consequences of Breaking Compatibility Versus Not Breaking It

We're very strongly committed to not breaking bindery tibility that the programs compiled before in the bindary form keep working. So where we can look for trade offs is with people who want to compile things that used to compile before without any changes. There are some very minor things that can be adjusted without harming many people out there. And i think, well, every time we find something like this, we'll think hard and maybe sometimes change something there.
