Buried in the notes is a small, but useful addition to the testing package that allows your test helpers to register their own cleanup functions (testing.(*T).Cleanup). I wrote a blog post discussing it in depth here: https://www.gopherguides.com/articles/test-cleanup-in-go-1-1...
Wish the json.Register funcion had been in 1.14. Desperately need it for a project I'm working on. If anyone has any ideas for overriding structs in a pkg I'd love to hear them!
For others following along - this is https://github.com/golang/go/issues/5901 to register custom marshallers on an existing `json.Encoder` instance. I feel like it's generally possible to work around this by creating a wrapper struct with an overridden MarshalJSON method? But maybe that's infeasible for deeply nested structs.
That's the crux of my issue. If it was only for a single, un-nested field then it would be trivial.
I am currently solving it by walking through the whole struct, but that is not-ideal.
