> More expressive representations of source code enables better merging. Merging is usually easy regardless of representation when all changes are comparatively local. The problem is always merging big far-reaching changes like a complete refactoring of an entire module, and I don't immediately see how any non-text representation would do significantly better (by a wide-enough margin to justify changing paradigms) than text at assisting with the merge process in this case.
