Hana is really about heterogeneous data structures and algorithms. While
technically possible, using Hana would incur a higher compile-time cost,
and the solution would most likely end up being more difficult to properly
optimize for the compiler. The bottom line really is that if you don't need
heterogeneity, you're probably better off using a bare bones solution than

Do not forget that I have spent a significant amount of time working on
Hana, without which it would have taken me much longer to write this
prototype. But thanks for the kind words anyway.
