Type systems are great: they catch huge swaths of bugs at compile time, and contribute to a grammar/vocab of forward development for your app.
Like type systems, modern tools for verifying correctness leverage structural descriptions of the problem, via graph-structured model of the domain: Type systems describe programs as a graph of types, functions, traits/etc, and their relationships.
Types are nodes, with relationships like returns, accepts, implements, etc as edges.
