- coldtea 9y agoHe learned the wrong lesson then. Which wasn't "don't break backwards compatibility", but: 1) If you break it, break it for compelling reasons. 2) If you provide a tool to convert, don't make it as awful as 2to3
- bonzini 9y agoBreaking language backwards-compatibility is one thing; breaking the extension API is less problematic, and breaking the extension ABI is better still.
