Hi Dan, What you are referring to is called *behavioral types* (see, *e.g., * https://www2.ccs.neu.edu/racket/pubs/fse01-flf.pdf).
If you want to go that route, you need (usually arbitrarily complex) behavioral contracts (not to be mistaken with the term type contracts used here) and static checks (*e.g., *based on abstract interpretation of a program). It would be super cool if Go2 natively supported behavioral contracts and check some of them automatically, but I doubt that there is enough resources/will/motivation. For example, behavioral contracts are a great fit for matrix operations as you can observe in Numpy and OpenCV libraries. (In case you want to use behavioral contracts in Go1, we developed https://github.com/Parquery/gocontracts to help us deal with contracts at run-time, and hope to start working on a Go tool based on abstract interpretation in some 2-3 years from now).
