looks reasonable. Can you think of any ways to test or validate that these types produce the correct puzzle hashes? It seems you have somewhat of a protocol (with the name curry_tree_hash()). Perhaps a macro could generate a test that ensures the tree_hash() call generates the same hash as generating the full puzzle and tree-hashing it.

It might even be possible to have tests that execute (generated) puzzles with their (generated) solutions and ensure we get the conditions back that we expect.
