I'm curious what experts think too.
So far I just guess it is because of clean type system getting
better hints for optimizations:
* it is easy to mark stuff strict (even in function signatures
etc), so it is possible to save on unnecessary CAF creations
* uniqueness types allow to do in-place modifications (instead
of creating a copy of an object on heap and modifying the copy),
so you save GC time and also improve cache hit performance
